<human>: We're long distance since he's attending law school out of state. He's always been a bit of a loner, and in all the years that I've known him he's never held long text convos. Well, until recently. The last time I saw him (6 months ago), he wouldn't let me touch his phone. Normally, he doesn't care. I didn't think too much into it bc we were in a bad place at that time. Time passes and we're better now. Recently, he asked me to DL whatsapp. Now I see him on ALL the time. He's suppose to be studying hardcore for his tests but ya how is he gonna do that when he's always on. 

That's when I started wondering wth is going on. I asked him about it and he said he has a group chat with friends. Ok cool. But now I'm noticing he's not answering me or taking forever and won't answer questions when I ask. I could be just paranoid, I dunno.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Antisocial fiancé suddenly becomes social, but leaving out who/what he's talking about when in the past it was normal.
