My husband and I have decided to separate after 17 years of marriage. We are still very amicable and he is staying in our house until he is able to work out where he will go. To keep the story short, we haven’t had sex in at least 5 years, and recently he began communicating with his high school girlfriend. It was pretty innocent at first (I’ve seen the emails,) but once we decided to separate about 3 weeks ago, the relationship has escalated. Yesterday I found text messages where they talked about him moving to where she lives, some financial things related to me, and more intimate message about when they get back together. I am feeling like I may need to start protecting myself financially - he has had mostly self-made financial problems for our entire relationship, and because I know there is the possibility of him getting money from me, I am concerned. Early this morning, though, we were both up - couldn’t sleep and I was feeling very sad and sentimental, we started talking about the good things and how concerned I was he was going to forget me, things progressed and we had sex (thus the “not thinking” part.) It doesn’t change our decision but I am now concerned that it could be an issue if he does try to get money from me. Can that affect things?
