Is it abuse?

There are several forms of abuse. A lot of times when me and my boyfriend have an issue, and he's still mad or even if he seems ok hell ignore me. Anywhere from all night to days. Never went past 2 and half or 3 but still. I have abandonment issues and it gives me MAJOR anxiety when he does this. His dad says he does this to everyone in his family, and he even admits it's terrible that he does it.. And I just don't know what to do. First time it happened he assured me he'd try to not let it happen but it did and I know I can't change a person only inspire them to want to change how do I go about doing it? Talking to him? I've told him about him ignoring me indirectly about it hurting me cause I'm scared to be blunt but idk maybe it's time to tell him how shitty it makes me feel
