Can a marriage be saved from 10 years of betrayal?

Yikes...take care of yourself. This is not just another woman but men.  How long has he been leading this double life?  I would be afraid.

123...Yes i have been tested twice already. And yes it is very complicated...he wants to stay married...he is an excellent father...and yes sex is not the whole part of a marriage. We have considered a separation but financially we are not able to do that right now. The first week of Dec he will be with Dr. Weiss at his center for 3 day intensive therapy. after that we will have one on one and couples therapy with Dr. Weiss via phone. What i wonder sometimes is i understand how he has gotten to the place he is and he is a wonderful person without this disease but even if he beats this...will i ever be able to let it go. Not think about the past at all. i guess as time goes by things get easier...right now it is just hard to see that far and yes i know it is one day at a time and the past is the past...i have been told. But the heart and mind dont always think the same way. :(  Thx for the concern for my health...he has been checked also.

I agree -cheating is cheating.....  Look out for you!

I also agree with what Good Gal said.  You need to remember he is a consistent cheater!  Most likely will continue to do so.  Really try to think of yourself and what is good for your life.  Yes, it is hard to be on your own (I am doing it) but you are still young and a wonderful future is ahead for you.

Sex with anyone other than your spouse is cheating. No matter if it's same sex or not. It doesn't matter if it's oral/mouth or genital. Disease is disease and cheating is cheating... I hope you get tested.
This has to be difficult for you living with someone who is supposed to love and cherish you as his wife for 10 years of lies and infidelity and betrayal. 
This is a great place to read what others are writing and respond to others. In responding you will begin to answer a lot of your own questions and in reading others blogs you will see patterns and if it's worth staying in the marriage or not. 
I personally would not be able to deal with the infidelity. I don't do well with lies and deception in general.
Even with years of him going to counseling is there a good prognosis for him?

Have you found a great counselor to help you work through this? 
There is a book called Too Good To Leave - Too Bad To Stay by Mira Kirshenbaum. A quick read and valid question and answer sections that help you look at and face what's going on in you. 
Good luck to you. 
Take Care.

It is more complicated than to have him stay or go.  Does he want to stay married?  Is he showing that he does? Is he a good Dad? Does he pay attention to you? Sex is not the whole part of marriage.  I would go to counseling by myself and with him.  This is if he wants to have a marriage.  If not he may need a separation to pull himself together.

I am sure you have, but I still need to say it have you been tested for all sexually transmitted diseases?
