Boyfriend problem

So I just broke up with my boyfriend of 3yrs reasons were that I didn’t feel like I was getting enough attention I felt like everything was on me like if he was mad he wouldn’t text me for hours or if he didn’t feel like speaking he just wouldn’t text me also if he was mad he would just text me good night and Goodmorning and this would go on for days. But I can’t say that the relationship wasn’t bad when we were good but he had been doing this since we started dating and I’m tired of it. And I don’t know how to feel I NEED HELP!!

Also if I were to do what he does it’s a bid ass problem
