Should I ghost my friend?

For the past week I’ve been feeling like I need to just remove this person from my life. We have been friends for about 3 years but anymore I feel like i’m the back burner friend (which he’s even agreed with 🙄.) He started going to college about a half hour away and of course made new friends, which is expected. I was happy he made friends down there and I understood that we wouldn’t talk as much which was okay. Anymore, when I would message him telling him about something that happened at work or with people we know all he EVER answers with is “LMAO” or “oh no” and never engages in a conversation. When he came home for christmas break we would hang out and then 20 minutes into it he would say he had to go because his college friends wanted to hang out. The past couple of times he’s reached out to me were because he needed something. He needed my advice on going to court and needed me to call him at 4 am to help him get out of a tinder hookup situation. I truly want to just ghost him without an explanation, because I highly doubt he would even notice.
