did i overreact?

UPDATE: i’m giving him a chance, but that doesn’t mean i won’t give him that trust he thought he had. i know you’re all going to get mad at me for staying with him and not dumping him but i have that type of love of where no matter and no matter how many times they prove you wrong, you’d stay by their side.

he needs to earn that trust back, he has very little respect and he’s on thin ice. he does me wrong and it’s over, i’ll let you guys know.

so my boyfriend was “sexting” a girl he knows and he told me this morning. he said he had no idea and that he didn’t know she was serious. i believed that but then he showed me the message and said “it’s obvious she was joking” maybe she was maybe she wasn’t. he said that she want to fuck him at school and that’s kinda weird and i don’t know who this girl is, we live in different states, but he went along with the “sexting”

after i kept giving him 1 word answers because i’m mad at him, he spams me and says how much he loves me and that he would never do anything to hurt, then proceed and i quote “if i were to ever get my dick sucked, it would be from you” i can’t make this shit up, he actually said that. i told him that joke or not he still shouldn’t of went along with it, it really hurt me and i told him not to talk to me for the rest of day. he’s not even allowed to say goodnight to me idc but now i’m thinking i went too far and overreacted.

i’ve had problems with trust and stuff like that in the past, he doesn’t know that but my heart broke a little more when he told me that. i’m really pissed and stuff, i just don’t know what to do. did i do the right thing? did i just act like a total bitch? idk i just need someone to at least tell me i did the right thing.

EDIT: here’s the convo, i did not do any work for the whole day

ÉDIT 2: this is their convo, it’s not much but it’s all he showed me so idk if there was more to it, but nobody just starts out the convo like that
