Why does he make plans and then cancel on me?

Anonymous
I’ve been seeing this guy on and off since the summer. He was really keen at first, going out of his way to spend time with me. He was thoughtful and always brought me presents, and then further down the line I noticed he wasn’t making as much effort. In the end we slept together a few times, and then he travelled to see me and we had sex for a few weeks. Then since he got back home, he’s been really cold and distant with me. The last time I spoke with him he was really cut off from me, and I tried to hug him and he wasn’t as responsive to any contact. Then he recently made another plan to have me stay over at his, (I didn’t initiate) and then cancelled it last minute.

i feel really messed around. What should I do?
