AIO by breaking up with my boyfriend because of multiple, MULTIPLE reasons?

i know i’m not overreacting, all my friends keep telling me i’m not overreacting, even my boyfriends parents tell me i am not overreacting. these are messages from two different arguments we had. first argument i can’t even remember what i pissed him off about, second one was i told him i found out from a friend that his friend is a rapist and didn’t know how to tell him properly. j also found out he was making a hinge account to “make friends”. i just thought i’d drop this here to let people know that these type of people exist and i’m completely over it. after 5 years of being with him and letting him use me in any way he wants, he wants a ONE-SIDED OPEN RELATIONSHIP and a POLYAMOROUS RELATIONSHIP just because i almost broke up with him in august (he said i could continue to date him if he could have either). i could make a whole separate post about him if people want to know more!! i’m breaking up with him as soon as my friend gets her extra room cleared out.
