20 F. Broke up my 2 years old relationship today and kinda feel guilty and regret doing it.

My boyfriend constantly used to stop me from wearing dresses like crop tops and lehenga's, stopped me from talking to my brothers and also did not allow me to go to gym and instead asked me to talk with him during that time instead of going to gym or parks. He is an orphan and had no one and At first I thought he was just little possesive but it turned worse these years. Forgot my birthday and told me that he is not interested in wishing me and why should he wish me. Told me that everyone left me because I was a bad person. Also said that he would be happy if I never came in his life. Called me a failure and said I wont be able to do Sh! in my life. He used to ask me why wont I let him touch me when We love each other. Today I broke up with him and he threatened me that he will commit something bad with himself. I feel guilty and regret leaving him. I need suggestion whether I did good or bad. (His nice side was he used to pay for me when I was hungry and was available for me 24*7)
