Friends until inconvenience

Recently I've had issues with communicating with a friend of mine and I learned that it was because he got a new girlfriend.

He said he was sorry for not responding to my texts and that he wasn't "ignoring me" but was just busy.

As he asked me how I was I explained that I had been trying to reach him because I had to go to the ER and stayed at the hospital for a week. Also that I have to have my next surgery very soon.

I could tell he was being very distant and didn't ask me any questions about the situation. I feel he doesn't care about me anymore because he made a move on me and I declined because I was seeing someone else and I'm demiromantic-Asexual. But he said he understood and he wasn't hurt. But, I always felt that was a lie.

He still hasn't responded to me and I feel like he's not going to unless I start it. So, I don't know if I should text him over the holidays just to be nice and see if there's anything left between us.

I feel no one cares about me unless there's something they want from me.
