Old fwb

My husband and I had separated a couple months ago and just recently got back together. During our separation, we each had a FWB. Anyway, mine knew my husband had been abusive (which my husband has so far done well about not getting angry). He talked and talked telling me how terrible of an idea it would be to get back with my husband with him being like he is. Because I could end up dead. So as I noticed my husband becoming a new man, I stopped all contact with the fwb to work on my marriage.

Yesterday he messaged me on Facebook asking what I was doing. I told him moving. He asked if I was moving in with my husband, I said yeah. And he sent wtf man, and that was all he said yesterday. Today, he sent me 4 long messages telling me how dangerous it is to be in an apartment alone because of things that have happened before. And we talked for a minute and then he had to work. I just don't understand his reactions. We had already established that we didn't want a relationship, so surely it's not anything like that. I just don't get why it would make him so mad. Ugh men 😂
