Left my(25F) boyfriend (27M) because of his gambling addiction.

So we have been dating for 1.5 years, and the trait I liked best about him was that he was caring and emotional. Everything was going well, and he treated me well every day and always made sure we’d resolve arguments the very day we’d have them. But since about January, he started online gambling, and it was alright at first. He would stop playing after winning some money and was still very present with me. But I slowly started noticing changes, like the way he would get really mad whenever he lost any money and be in a bad mood the entire day. If I raised an issue, he would get mad cause it was affecting his game and hang up on me, then call me back only after he was done gambling. I felt so disrespected and cried almost every day for months because all my attempts at communication failed. We are in a LDR and stay together for a couple of weeks every two to three months. When I stayed with him recently, he was so consumed by the gambling. He was not present with me, would be gambling even during dates but when I would bring up breaking up, he would get so upset, tear up and swear I was the love of his life. It’s just gotten worse since, and I have been so drained emotionally because I feel so unheard and alone. We had a fight two days ago and I couldn’t take it anymore. I lashed out at him and broke up with him. That was it. He hasn’t contacted me since and I know he must be gambling sitting in his couch while I feel anxious and hurt every day. My mom says he doesn’t deserve to hear from me again. I miss him alot but hate him for treating me so badly for months. Should I go no contact and just try to move on? Please give me advice.

TL;DR! – left boyfriendf with gambling addiction, need advice.
