Why does he text me but seem distant?

Anonymous
There's this guy, we've known each other for 11ish years and have always liked each other and have talked on and off since we were about 12. Nothing has ever come of it. We've both had other relationships, but it seems like whenever we're single, we start talking again. I moved out of state recently, and we're talking now, but it's hard with the distance. If I was closer, I would be able to visit, and I think things would be less confusing, but for now I'm here.
Anyway, him and his ex broke up, and he messaged me. This was 2 months ago, and we talk every day and flirt occasionally, but he's also pretty shy. Lately, he's been acting differently. Putting less effort into conversations, not being as flirty, when we snapchat he doesn't ask to see me anymore, etc. It seems like small stuff writing it out but it's kind of a big change from how he was up until a couple weeks ago. He always texts me first then does all this stuff and it feels like a lot of the time he doesn't even wanna talk to me, I carry the convos and when I get tired of doing that and act like him he doesn't put any effort and sometimes leaves me on read for the rest of the day. He'll message me the next day and then it just seems like he feels obligated to. I tried asking him recently but he said he's just a boring texter.
I've asked a couple friends and they all said he wants me to show that I'm interested more and I try to, but when I do I don't think he picks up on it. I'm almost about to give up. I'm tired of this lately and I don't even know how to bring it up to him in a way that I would get a straight answer. I would like to know that we're either working toward a relationship or we should just end it before we get more invested, but what does it sound like? Why would a guy feel obligated to text you when he's not interested anymore? I'm tired of awaiting his texts and getting so excited just for him to say "yeah" or something. Should I try bringing it up again or just leave it alone?
