I'm thinking of ghosting my friend
Why do you want to ghost your friend?
I think he's getting too needy lately
It's rude to ghost your friend and make judgements about them. If your friend is too needy maybe you can set some boundaries with him? It will help preserve the friendship while making sure both of your needs are met.
I don't think I can handle all of that. I'm going to ghost him.
Your friend being too needy is indeed a problem for you, but remember that if you simply cut off communication, he will get worried and confused.  This will just make him reach out to you more often, and beg your other friends to do so on his behalf.  It will be easier for you if you just set boundaries, and tell him No from time to time.
