When does the emotional roller coaster stop?

I don't have any advice for you, but wanted to say that I'm in the same spot, asking the same thing about the rollercoaster.  The majority of the time, I'm perfectly fine and content but every once in a while, it hits me.  I miss him so much it hurts and feels like it is taking my breath away for a moment.  Then I think about "us" and cry a little, then I go back to being happy.

I'm finding, as others suggested, that focusing on what makes me happy and thinking about the times that I am content is what gets me through right now.  Being so early in the process (we've only just seperated), I have no doubt that this will continue, but ultimately I know in my heart that I will be okay whether we work it out or we divorce.  That self reliance and independence is what gives me peace, even when I'm hurting.

Hang in there!

I wanted to thank you all for the great advice. I thought the roller coaster may be a long ride! I think it helps a little bit that we never had children so we will not have to see each other after the divorce is final. I think what will be difficult is that we grew up together and have many mutual childhood friends. We no longer live in our hometown, but return frequently.

I just want to get through this with my sanity!

Time heals all. It will get easier but it takes a while to work thru the emotions.
Find a friend to talk to....keep your self  busy. Stay on here , there is much advise and support in here!

I do not think the emotions will ever stop, but they will get easer to deal with in time.  Just allow them to happen.  If you have kids I can tell you the fustration of dealing with a ex can be rough, but it can be done.  It will take a lot of time and effort to be nice to each other and not want to kill or go on the defensive mode.  Keep positive attitude and remember why you split.  Things get better, this I can promise, it take time and a lot of it.  BE good to yourself and be selfish at this point.  take care

The roller coaster won't stop for a while. Some things will cause it to smooth out and then some will take you for a loop. When you feel like its smoothing out a little remember what made you feel that way and concentrate on those things. When I start to hurt and get to feeling that lump in my throat I have to tell myself to stop thinking about what it is that made me start feeling that way again. I tell myself to "STOP IT". I try to find a comforting thought to go to in my mind. Knowing my wife wants a divorce really hurts. I've come across evidence that she's been, at least, talking to an old boyfriend. When I think about that it really hurts. I know I can't do anything about it though. To "STOP IT" I have to think about something positive about this. Even if its as little as the fact that I won't have to use the utility bathroom because our master bathroom is a complete wreck and can hardly be walked in without tripping over clothes on the floor and brushing my teeth in a sink that won't drain because of all the hair in it and taking a shower in a shower that has 15 shampoo bottles and 3 half-used bars of soap on the shower seat with slime from never being cleaned. It's something positive. Toward the end of my living there I could do nothing right, no matter how hard I tried. I don't have to hear all the put downs now. It helps to think about the things that you can do something about. The loops will still come but they can come less often. I have had few people to talk about this with. I've talked to God and prayed for help. I've asked him to keep me focused on what I CAN do not what I CAN'T. You can do it! Good luck.

You will continue to be on the emotional rollar coaster for awhile I hate to say.  I learned in a divorce support group you go thru stages of divorce and it's an emotional rollar coaster for awhile until everything is settled down, you go thru court and everything is finalized.  I'm not sure if you have children or not but if you do and he doesn't see them for visitaiton and things like that, then the emotions start all over again.  But it does get easier as time goes on, when you get used to being single again and on your own.  It helps alot to stay busy and focus on something else, to maybe try out a hobby you haven't tried before or go see a chick flick at the movies by yourself or with other girlfriends that you couldn't watch before.  My divorce group said to stay busy with friends, co-workers, hobbies and make a list of things that you've done and things that you would like to do in the near future (or places you would like to go), that helps out to.  Even when you know the divorce is coming it's still hard.  I knew mine was coming because I caught my ex cheating and I definitely wasn't taking him back after that!  One strike he's out!!  It will get better you just have to ride it out.  I wish you all the luck!!
