BF what to do

So I'm dating this guy, and at first he was so into me. We'd hangout pretty frequently and he'd message me all the time. Now it's almost 2 months into it and he just never talks to me like I message him and hours later he's like "sorry didn't see you message me" or I'll message him and it's a short answer back and now I haven't seen him since like the 9th. I'm just annoyed like clearly a guy would wanna see his gf right? I'm just ready to call it quits if he doesn't even care to make me a priority. Like he wanted me to be his so bad and now he just doesn't care. Its so annoying. What would you girls do?
