AITAH for deciding to let HIM come to ME? - Lemmings.world

I (F15) liked this guy (M16) at my therapy group since I was 13 in 2023. He left the group and the group ended with the therapist leaving so I thought I’d never see him again. I got his contact information and he started to like me after a while but he had a boyfriend and they weren’t in an open relationship, so a typical one for teenagers. He broke up with him about a month or 2 ago, and he started to like me. Now we are dating. He has been leaving my messages on “seen” constantly (meaning reading them but not responding), probably because he’s busy. Since I have a bad past with people being cruel to me for texting too much or just being told “can you not text me?” I am scared that will happen with him, so I decided to let him text me first because I’m afraid he might feel bombarded. AITAH? Am I being, like, dramatic? He does this for days, by the way, only responding when it’s convenient or important.
