Should I be mad?

So my ex husband and I had a really toxic relationship due to his drug abuse for years. I divorced him in April of last year. Well In September things got real bad with him and he ended up in jail. They sent him from there to rehab. He was doing better so we decided to try to work it out. I thought he was changing. They sent him home early temporarily due to covid 19. Things just haven’t been that good. He got Facebook back and he won’t block his old drug buddies. Which made me suspicious but he said I want them to contact me so I can show you my response I was like ok but still don’t like it. Some of these buddies are other woman that he was with during his drug using days. Anyway he wouldn’t accept my relationship request. I had been asking him for days to accept it but he just said I will later. He finally did after I got mad and deleted

It. The reason I’m upset is because I feel like he wouldn’t accept it so once These people saw him on FB it wouldn’t say anything about me! Made me feel like he wanted him cake and eat it too. Am I over reacting?
