How do I tell him

Me and this guy have known each other for a while and we just started hanging out and he would pay for things and everything for me we used to talk everyday but lately he doesn't seem like he wants too we hung out last week and I know he has an interest in me he hadn't text me and three days and I finally texted him yesterday and he said his phone had broke which I believe he's not a liar we talked yesterday a little and I texted him today in in the morning but he didn't respond he's been on Facebook I'm going to text him and ask him what's up but how should I say it? I was thinking

"We don't talk as much as we did and I feel like I'm bothering you, do you not want to talk anymore"...

How would you text someone in this situation... we are close friends and we used to talk all the time everyday that's why I'm asking him I don't want to lose our friendship... I'd usually just leave the guy alone and not text him anymore...
