Should I Just end things ?

My boyfriend and I live together and he has a daughter from a previous relationship. The mother of his child is constantly harassing me, stalking my social media etc. Calls his phone all day and night starting shit with him. He pays child support and gets the child when he’s supposed to. One day she popped up at our house kicking in the door and damaged it. I called the cops but didn’t follow through with the charges. Hoping she will get her shit together. Anyways she always tells me he wants her... her calls her wanting sex etc. which isn’t true because we share phone accounts and I see it all. We pick his daughter together. Smh I try so hard not to use the “B” word with her.... but she’s just that “BITTER”. But after 2 years of dealing with him I have to deal with her and her bullshit. I just wanna call it quits but I really do love him. But absolutely hate the drama
