I’m very sorry for your pain. The reasons you give for the breakdown of the marriage do sound surmountable, but the challenge in relationships is that it takes two people to make them work, and only one to end them. So if she doesn’t want to work on the marriage or stay in it, there’s not a lot you can do. If she is willing, then my advice is to address the issues she finds problematic. Your sex life has broken down, and getting that back on track is important. You have to win her back and seduce her, but start small, with romance. After 10 years of marriage, it’s very easy to lose each other, and familiarity is the antithesis of lust and romance in many relationships. So work against all that. Surprise her. Woo her. Try and seduce her. I know it will be difficult after all this time and animosity, but it’s one way back in. Then consider the things you mentioned she feels were postponed, and address them. Take care of her complaints and figure out what makes her want to leave that you haven’t mentioned. This is a case of two people who loved each other, losing their way. Really look at what she thinks she is going to gain by divorcing, and see if you can give her those things in the marriage. 🙂
I hope this helps. Let me know if you have any more questions.
