Hi, sounds similar to my situation. Second husband of 16 years is leaving. He suddenly blames me for everything. My first divorce was due to ex’s infidelity. He doesn’t want to work on fixing the marriage. He said he’s just done. How can someone you love suddenly become a stranger? He is staying until he finds a place to go and told me if I say anything he’ll walk away now. Very uncomfortable having him here and yet I don’t want him gone. Like you, I also feel like a failure. 😞
