Mad black girl

My ex broke up with back in January and basically put me n my teenagers out. I gone take it back to December when i got sick and was hospitalizedfor 3 days yes he called and text me he came by twice only cause i asked him to bring me some hygiene stuff. He started acting different once i got out hospital, i did notice in his phone he had been talking to ex wife well they still married which i found out because the whole 2 years we were togetherhe signed divorce papers twice put she never sent them in nor got notarized. But anyway on January 9th i remember him leaving to go get haircut come back home shower get dressed and leave and didnt say nothing, he was gone all day. Did i call or text him no. That felt weird to me but i found out he had went amd took his suppose to be ex wife to OUR favorite mexican restaurant, i didnt say nothing for a week and it was eating me up inside so i asked and he didnt deny it all he said was "AND". Every weekend after that he would leave home and stay gone and dont say nothing. I was like you shouldnt be talking to her unless it about divorce stuff. He just said i needed to talk to her and i said well im your girlfriend talk to me. Our communication had fell off a lot it was so bad he didnt even want to talk to me he would text me when he wanted to ask or tell me something.
