Just a rant

I have this one friend who used to be my main support system, but now he only talks about his friendship with this one girl he likes. She's a really busy person and sometimes leaves him on read for a day or two but she always responds again eventually. He won't let me complain yet he complains about this all the time and it's really annoying that he expects me to constantly comfort him when he 1. won't do the same for me and 2. won't listen to a word I say, only criticize me for not being more helpful when I'm literally trying my best not to just snap at him to give her time to respond. I love my friends but sometimes they get on my nerves and I have my own issues to deal with without them expecting me to give everything to them for nothing in return.
