Dating my best friend is hard

Well basically I started dating my best friend about 6 months ago and off the bat it wasn’t good because we both had just gotten out of a relationship and we were both dealing with depression and he had anger issues and I had/have trust issues but I guess we saw right past that. In the beginning of the relationship he treated me very poorly, got mad at me for the smallest things and would yell at me and cuss me out and I would just try to fix the situation by telling him to calm down and to just talk to me. I through out the whole relationship was accusing him constantly of cheating or being shady, I made him unfollow every girl on social media it was very bad, I’m just so insecure about myself so it’s just all around toxic till I started seeing change in him, he was able to control him emotions and actually talk to me but at that point I was so hurt by everything he had said to me in the past I lost patience and started blowing up on him and still had trust issues. The most recent fight that basically ended it all was that we both got extremely mad and started to say every single thing that we knew would hurt each other, from calling him a bum to him calling me insecure and it just got worse and I messed up because I went and added my ex on sc in the heat of the moment and my ex was also his friend so he found out the day after when we had said we would try to work things out and things just went really bad he said he was so done with me and he was going to get back at me and I tried to get him to stay and forgive me and I could forgive him but he was hurt and mad and acting so careless even sent me messages and pictures of him messaging girls but I partially feel like it’s not true because I know he’s hurting too he just wants it to stop but idk we kinda just left it at goodbye but then he messaged me saying hello and I responded with hey so I basically just need some advice on what to do because we both love each other a lot just hurting a lot.
