<human>: Can you succinctly summarize the text in 1-3 sentences?

I've been dating a guy (long-distance) for about 7 months. We're both seniors in high school, and I'm his first serious girlfriend. For the first 4 months, everything was absolutely amazing and we saw each other at least once or twice a week. Most of the time, he was loving and intimate and generally happy. However, for the past three months, things have turned pretty shitty. It has now been a month since I've seen him. He makes no effort to see me, he no longer compliments me or tries in any way to help me feel good about myself, he has hidden his relationship status on Facebook, he disappears and doesn't talk to me for long periods of time, his messages are always brief and curt (or he just trolls me), and he's admitted that he's not used to caring about people and that he doesn't care if we have sex. We used to be best friends and could talk to each other about any and every problem, and we've worked through plenty of other things. I'm trying to fix this, but it's starting to seem as though he doesn't give a shit anymore. I'm pretty giving and I care about him more than most people, but I'm afraid this is becoming unhealthy for both of us. I have problems with anxiety and depression, and I'll definitely terrified of ending this and being forever alone, but is leaving him the right thing to do?

Oh, and by the way, he just told me that he really wants to start playing WoW.
<bot>: My boyfriend seems to be pulling away. It's making me depressed and insecure. Should I give up and end it?
