Not sure if I’m thinking about me

Husband and I separated (his choice) I decided to join tne army and I enlist next week. I’ve had to beg him to see me, talk to me, etc. I was the one who made the effort to grow back together even though this is what he wanted. Been 3 months so now I learned to live apart from him, cause he wasn’t showing I wasnt what he wanted anymore. He told me he wanted to be with me AFTER I told him about my military plans. Why now? Wehrmacht couldn’t you tell me those things before I decided to leave? I got dinner with him tonight to tell him it was over but he brought up how he’s very distraught, can’t sleep, falls asleep at work, has digestive issues, isolates himself and he doesn’t know why or where it came from. I couldn’t bring myself to tell him that tonight. What do I do?
