Me And My Boyfriend. Good Times, Rough Times, ..idk?

ok well i’m going to tell you my story, cause i really need help.
my boyfriend and i met in school.
i was in a relationship, and he was new.
i was already trying to fix things with lets call him…adam*(fake name)
adam was a good best friend but i just got out of a relationoship where i was in love.
and was trying to get over him.
me intensions wasn’t to have a rebound, but adam did make me happy.
i just wasn’t in love with him and he was. so i felt like i had to fall for him, and i tried.
but my heart couldn’t.
when i met my current b/f now lets call him* nathen
it was like oh my god instant connection.
i admit i never cheated before.
but i will also admit i kissed him once while still with adam, but then i broke up with adam cause i knew i didn’t want to hurt him anymore, and i think he deserved someone who loved him equally.
no one liked that after me and nate started dating. but we stuck by each other through all the drama my friends made.
on the phone we used to talk ALOT. and about everything..but now during the summer, it’s been harder. my family doesn’t except him b/c of reasons and bc while we tried being seperated he tried talking to this other girl, but he and i came back to each other. though i know its his fualt to, she took advantage of him while i left for new york. they didnt have sex, but just kissed. which is still a cheat.
but i know i made a mistake and did it to adam.
and nate stopped it, she got mad and didn’t wanna talk to him.
point blank she told me she did it to hurt me..which is ****** up. but hey.
i love him and he promised never to do it again, but how many people say that?
alot you catch my drift.
he got slapped in my face by my mom, because he was in the house when he was’nt suppose to. but that was both our faults
thing is, i trust him. after everything we been through. but we argue more now than ever.
we’ll be on the phone and have nothing to say, but we’ll stay on the phone just b/c we’re on it.
i know a guy that gets talked about, who got slapped by me and my mother.been through hell just to stay with me, he gotta love me right?
why would someone stay for that?
i just wanna have something to talk about.
his past,
he been with his mom, his dad is an ex marine.
they split, his mom put him through hell.
(his dad told me)
he’s with his dad now, and they kinda bump heads also.
i think his dad takes out anger on him, and his job makes kim mad too.
what can i do to help this relationship.
splitting up woyld kinda be easier.
but when we do split we always get back together.
he told me he’s stupid for “losing his love..and that he wants me to be his girl b/c he loves me and he wants to show me off to the world like he always do”
so whats our problem..
we love each other, but when we brake up we run back to each other..
