I need help pleaase.:( boy trouble.

I don't think my boyfriend loves me anymore :(
he lives about an jam away from me, but we see each other almost every weekend. And during the week, we text/call/msn etc.
And he ALWAYS used to talk to me before I could even talk to him first. He was so talkative too.
He doesn't talk to me much anymore, unless I start to talk to him first, and Ive tried not to be too clingy.
Now, the conversations we have is..
Hi
hry
good u?
Good.
Andddd that's about it. He's always putting ':/' these faces in.
He doesn't say I cinta anda anymore, wen we talk on the phone, he talks to his friends with him, atau plays video games. I get about 2 words out of him.
Maybe he's uninterested in me now?
but in person, he asks for kisses and hugs and everything. To be honest, he's really pushing me to do .. That sort of stuff. He doesn't give me any choice.
His best friend and my best friend just recently broke up, (we set them up) and maybe that had effect on him?
They broke up coz his friend cheated on mine, and I kinda went off about that and I don't think my bf was really happy about that. And me and my friend told my friends ex(my bf's friend)'s NEW gf that that he cheats.
And my bf has been worse since that.
Do you'd think that that is why my bf is akting like this?
Hellpp.
