Or try the Healing Heart board which is for newly betrayed who are just finding out. There is a link on the left side of this page, in the upper left side. The mods will probably move this there anyway so that you will get more responses.
WELCOME! I wanted to say I am sorry for your pain and that you find yourself here, but we are glad that you found us. Please feel free to ask questions and post as much as you like.
You ask "when should I give up", if you filed for divorce it sounds like you already have, even if divorce is not what you really want. I have come to find that you cannot change anyone else. It is up to them to want change and to seek help to change. It sounds like your H ahs not done anything to change except make promises he couldnt keep. Unless he gets help and figures out why he continues to cheat, he will continue to cheat. Obviously he hasnt figured that out. Maybe IC (individual counseling) can help in that regard as opposed to MC. This is his issue and he needs to address it.
Take Care...Carol~
EDITED TO ADD: If your spouse is cheating he really isnt there in the marriage...you are already alone. I know this sounds harsh, and not what you want to hear. I have told myself the same things...I dont want to be alone...but I am alone if he is not fully in the marriage.
