Should i stay or should i leave

I met my boyfriend via Facebook on January. He hit me up “i like you and i would like to meet you” Our first meeting was at his house 😂 it was very risky but it was totally worth it. He made us both lunch and we spent hours together and nothing sexual or anything of that kind happened.
After a few dates at his house We decided to make it official on March.
He called me every night and depending on the day we’d talk for hours

Lately things haven’t been the same
He doesn’t call as much as he would
He’s so bad at communicating. I’ve told him about this and he says he’ll try change
He doesn’t give me attention he can be online and not even text or call.

The funny thing is:
I was never comfortable walking around butt naked with someone watching me but i can do that freely with him there.

If i ask for help or something he provides

The sex is great!

He is patient with me

He can tell me anything at anytime: there was one time he lost something and he just called me to tell me that

I love him so much and i don’t want to lose him. I’ve been thinking of breaking up with him because this whole thing just makes me sad. I cry sometimes wondering what exactly is going on.
If he has found someone else
Whether he’s lost interest
Or if thats just how he is and i just couldn’t pick it because our relationship was a bit rushed
