Maybe I just have a poor taste in friends

Friend 1 use to get mad if I ever left him on read, I'm talking always brought it up and made a deal about it. Fast forward to now he leaves me on read all the time even though he started the conversation. He never asks or really seems to care about anything in my life anymore. Yet will still message me a couple times in a week to tell me how bad everything is going in his life.

Friend 2 basically does the same. Last week he started a conversation then 3 messages in just dropped it for days. He will act interested in my life occasionally. When I tell him he barely acknowledges it then moves on to all the sad stuff happening to him. The worst was when my vehicle broke down and he knew it, I was in his location he didn't offer to do anything and didn't seem to care.

I know everyone needs someone, and I've tried to be there for them. This has been going on for months but I'm starting to feel drained and because of that I don't want to answer their messages.
