Not looking for advice on whether or not to leave him. Just insight on myself. Why this is happening and if anyone has had any similar experiences? I wonder sometimes if I'm too sensitive?

I just want to know if there's something wrong with ME. Not him.

My boyfriend, who knows how my ex was (knows and agrees he was abusive because he was formerly friends with him) and was nothing like him at the start, is beginning to show signs of being similar.

Everything was great until I started school. I think maybe the distance and struggle I have making time for him is a big factor. But if his personality is not like my exes at all, why would he treat me the same if there isn't something wrong with me?

I don't want to bring this up with him because I don't want him to know I'm comparing. That would hurt him a lot. But I do plan on opening up about our relationship soon and that I don't like how he treats me.

EDIT:

we talked about it over text (LDR) because thats the easiest way i can let out my feelings and assure i dont forget/say something wrong. if he argued with me, i probably would let him walk over me (i'm not confrontational and dont like conflict eehh).

not saying that he would, just i wouldn't argue my side enough. but here's his message:

he's not abusive and i know and have always know he isnt/wasnt. we were just out of touch.
