UPDATE - My (27F) boyfriend (28M) is obsessed with my ex (27M).

Original post
After my last post, I tried to take the advice in the comments and suggested couples counselling and I asked my boyfriend to cut off my ex, but he got angry at me again. He claimed I was the one who needed therapy because I had jealousy issues, and that my ex was one of his good buddies and I couldn?t dictate who he was friends with.
Then a week later he had another hangout with my ex and his friends where he proceeded to very loudly tell them how I was so insecure, and I was trying to tell him who he could speak to. My ex and Luke had to tell him to stop which he didn?t like at all. I should?ve just broken up with him at this point, but I was stupid and still clinging to the hope of my boyfriend going back to how he was. After this happened, my boyfriend was constantly making jabs at my ex and Luke but then he would still contact them and pretend to be friends with them.
Then, he became super interested in what my sex life was like with my ex. He was constantly asking me who was better between the two of them and he would ask me if I had done this or that with my ex. I kept telling him I didn?t want to talk about it and to stop asking me. I then find out from my ex and Luke that he had been asking my ex directly the same questions and that he had been bragging about our sex life to his friends. My ex said he was telling me because my boyfriend made a comment about loaning me to my ex if he ever felt like recreating old times. That was the final straw for me, and I broke up with him and moved out.
My now ex-boyfriend didn?t take the breakup well and he went on a smear campaign. He even contacted my family and my ex?s family to tell them we were apparently having an affair and that he had no choice but to break up with me. It?s been almost a month since we broke up and he keeps getting new numbers to text and call me.
Deep down I think I knew this would be how things ended. I?m sad about the relationship I thought we had ending but now that I?ve had space away from my ex-boyfriend, I feel much better and it's like a huge weight has been lifted from my shoulders.
TL;DR ? My boyfriend wasn?t willing to work on the relationship and he kept doing things to embarrass/upset me so I finally broke up with him.
