Two weeks ago, my DH of 12 years, announced he wasn't happy and didn't know if he could see us being together for the rest of our lives. This came as a complete shock and surprise to me. We have always been affectionate, supportive and loving towards each other. Our schedules are very busy (he has 2 jobs and is going to Uni and I work full time and look after our 11 yr old DS). We talked and decided to work on things, but I couldn't get past a nagging feeling that he wasn't being completely open and honest. He said he wasn't having a sexual affair, but he had snogged other women on nights out with his mates (I wish I didn't feel that this is equal to a sexual affair, but I do). I was hurt, but that nagging feeling still wouldn't go. Last night I was able to access his Facebook account and turns out, he's a serial sex-chatter. I couldn't even count how many women he talked dirty to, including some of my so-called "friends"! I confronted him and he admitted that he can't stop doing this, he's compelled for reasons beyond his comprehension and he feels a need to flirt and get female attention in order to validate his masculinity (those are my wordshe said "to make me feel good about myself"). He goes out a lot more than average and said he won't stop as this is his social life with his mates. To make matters worse, I have only just gone back to work after a 6 month sick-leave for severe depression after my father died and also was feeling extremely suspicious, possessive and jealous towards my DH, which he kept telling me was in my head. I've spent 6 months in therapy and taken numerous different anti-depressants to make it through all that and barely a month of being back on my feet and getting back to work, he drops this bombshell. He says he loves me but in one of those flirty chats he told another woman that when he's away from me he feels free and good about himself. So then he tells me he loves me but doesn't know if he's "in love" with me. I asked him to leave and we told our DS, who didn't take it well and it was terribly emotional for all three of us, and he said to us both that he couldn't do this, he would make this work. We've had ups and downs this last week and again he insists that he wants to stay and try, but there's no communication from him towards me, he won't look at me, doesn't touch me, and we definitely aren't laughing with each other like we normally would be. My DS is desperate for us to stay together, I'm heartbrokenliterally, I feel like I have no more tears left or strength to maintain the struggle, and DH is walking around like a condemned man strolling down the Green Mile! Can someone offer up some sound advice, please?
