Leave the other woman alone. It will lead to nothing but trouble. You should really talk to your wife and have an in depth conversation. I completely understand where she is coming from.  Her sex drive may just be down. Some womens bodies and libidos change drastically after children. I know first hand since I've experienced it. Just work together and you guys will get over this hump. But hooking up with someone else will not solve your problem, it will just complicate your life unnecessarily. And by the way the chick you work with who says she is in love with you is lying to you. She saying what you want to hear to get what she wants. Beware of the shark at work.

Maybe you need to make your wife want to have sex with you.  Why do you even have time to go out and have drinks with another woman? Make a date night once a week with your wife and go dancing or a nice dinner, make her feel special and attractive.  She knows that you are not putting her and your children first so this does not make her feel close to you.  If you help her around the house and with the kids she might feel something more for you and actually want to have sex with you.  You need to end it with the co-worker before you lose your family.  it is not worth it.  Put your efforts into your wife and kids not this other woman.  I am sure the co-worker is attracted to you because she can not have you, once you are available she might not be as interested anymore.

"...go out and get drinks..." - Actually, the truth is that your wife is indeed quite tired and unwilling to have sex with you; although, it is not for the reasons that you have heard:

• First, the children are cleaned, dressed and provided breakfast... But, not by your devoted spouse - it is by the man that has replaced your role of father to your children.
• Second, the children are shuttled off to their activities... But, not by your devoted spouse - it is by the man that has replaced your role of father to your children.
• Third, your spouse is unable or willing to have relations ("sex, as you put it) with you... But, of course, she is at the spa entertaining the thoughts of how her even will be once the man that has replace you as husband walks back through the doors of her new home and life... Her thoughts of wonderful night with dinner and dance do tickle her delight... Conversation and interest... Caring and thoughtful... What in the world would she want to do with someone like you that is willing to disrespect her in this way...

She most likely does need some additional motivation in her life; and, from your selfish attitude and behaviour, she will most likely not find the inspiration from you...

Yes, have the affair with your co-worker to better understand why you are unable to have the intimacy with your life's partner... I wish her well in her brighter future...

Sign me "uninterested in your life"...

Maybe you should talk to your wife about going for a check-up with the doctor.  Her fatigue could be a sign of something else.  A woman doesn't just have sex to please her husband; she has sex because she has needs too.  If she's not having sex with you it could be something more than just being tired from taking care of the kids.  Talk to her about this and go with her to the doctor and speak frankly with the doctor about how this is affecting your marriage.  As for the other woman, well, i think deep down you know that's not the right thing to do and most likely you don't want to act on it.  If you did, you wouldn't be asking for opinions.  Remember, the grass isn't always greener on the other side.  Good luck.

Everyone's work day is full of stress, and we all usually have some kind of money issues to deal with as well. Raising kids full time, keeps you smack dab in the middle of all your stresses at one time! Finding time to unwind and leave your work day behind you is hard, when you live where you work!! I know that I was often too tired to even think about sex, after an exhausting day of nurturing, and it takes some work to be able to flip out of mom mode, and feel seductive enough to get into the mood. I would suggest first of all, that going out for drinks with any woman, is a bad idea, unless your wife is right there with you, this is just asking for trouble. If you want to fix the bedroom issues, you should try making your wife feel wanted...not groped, or like she's got a duty to perform, but truly desired. Have you ever tried a full body massage? I know that works for me. Even when I'm too tired, there's just something about a light touch, and kisses on the neck that get my motor running, and I eventually forget all about being tired! What better way to help relieve her stress, make her feel sensual, and get the results that will leave you both feeling completely satisfied?!

One thing you shouldn't do is act on your interest in this other woman. A co-worker none the less. Be a friend to your wife first. Back up for a moment and think about what you are saying.  Think about what your wife is telling you.  She might be asking for  your help.  And even if she is not, help her out anyway.  Family and home is a full time job too, regardless of our careers.  You should, as was stated in a couple earlier replies to this question, Take control for a week or two and let your wife breathe a bit. Offer her some get away time.  Girls night out or, a babysitter and you two take a night a week and get to the issues that concern you and her.  Which there are if you are out drinking with another woman and she is opening up to You about Love?  Like I stated earlier. Take a moment here, step back and think of the damage that would cause your marriage.  Your wife is the one you Love?  So Love Her

tell your wife that you will be taking over all parental responsibilities from the minute you get home at night...and then really do it.....for a week or two or a month even....tell her to go out with friends, to the spa, shopping, whatever.   if things don't get better, than there are deeper issues than just tired.

If you would put as much effort into your marriage as you do with your co-worker you might be scoring on a regular basis. Of course the co-worker looks appealing to you right now. She is readily available to go get cocktails or do whatever your heart desires but I wonder if she would have the same drive and determination if she had spent the whole day

chasing kids, cleaning house, running errands, doing laundry, cooking dinner etc. I doubt it. Maybe you should pay for a sitter or better yet you come home after work like you should and give your wife an evening off  once in a while. Let her get together for a couple of hours with her friends or get a pedicure or go to the mall or a movie or maybe just a long drive alone in the car. She needs a break badly . You need to remeber THIS IS A PARTNERSHIP. Trying to turn this into a tryst is only going to destroy your marriage.
P.S. Have a drink with your wife. She might need it, she might enjoy it and you might get lucky.

I'll tell you exactly what to do. Stop any and all social contact with this woman at work and instead spend time helping your wife care for the children. You never know this may give her the extra energy needed to have sex once in a while.
