(Ex)Boyfriend called me a whore

My boyfriend doesn't want to have me on social media even though I've insisted we do. He follows a bunch of girls which I can't prove but I am sure he speaks to. We took a break and he followed 26 new girls and as retaliation I also followed back some guys. I dont speak to the though.

Last night he started telling me how I am a whore and slut for following guys. He said "hoes will be hoes. They're everywhere."

I tried convincing him I do not talk to anybody, even offered my passwords and he didn't want to. I've always been very open with my social medias and phone and he knows that. I started to think he has somebody else and that's why he chooses this topic to argue and leave me. He breaking up leaving me
