idk anymore

so me and my boyfriend been together 7/8 months now.. been living together awhile now. and the other day he was walking to the bedroom and i ran to him and was gonna jump on his back but he turned his head and when he did my hand hit him in the lip.. and now when we kinda get into it he says “what you gonna hit me again” after i told me 100 times that it was an accident and that im sorry.. and today i texted him i love him and he said “no you dont, all you do is yell at me, like you tired of me or something, like you dont wanna be with me anymore” i just feel like he’s not happy with me anymore. idk what to do. i dont want to lose him bc he does treat me good. every relationship isn’t perfect there’s days when we argue and that’s rarely.. i just dont know what to do. im crying just thinking what if he isn’t happy with me anymore. 😔 and on top of everything i might be pregnant too.

UPDATE: we talked everything out & i found out that im for sure pregnant ☺️
