Am I in the wrong? Lf brutally honest people

Before my bf and I started dating I had two discussions with him:

1. I’m not okay with my partners being in contact with exes, past hook ups, dating app matches, past fwb, past sexual or romantic interests. He agreed and was praising me for thinking this way because he feels the same as I do.

2. I’m not okay with dating someone who is capable of dating multiple people at once before finding someone serious. He also agreed and was relieved to find someone just like him that can only handle one at a time.

6 months pass and I find out he stayed in contact with exes and fwb, and he was talking to another girl from tinder 2 days before he asked me out.

It has caused a never ending fight that pops up every month for 6 months now (1 year together). He lied to my face about what he said to his fwb and created an elaborated lie even though I saw him tell her he wanted to fuck on a public post on twitter.

I can’t trust him and he has done nothing to fix things except quit using twitter. He says that’s good enough and proof he isn’t doing anything else. He says that at this point I’m abusing him for telling him I’m still not fine with it.

Am I in the wrong? I tried to make it work. Am I supposed to shut up and act like everything is fine? I wish he could leave me so I don’t have a reason o keep going back to him.

He says he’s not capable of cheating now that he removed twitter and “talks to no one” even though I’ve caught him talking to girls and initiating conversations because they post memes and he find them hilarious. He has removed our pictures together and never shows me off but he reposts his Twitter girl images. He says I’m abusing him because I never stop bringing it up. Am I?
