Is OTHER wrong in the post ? POST : Firstly, sorry for formatting, am on mobile.

John and I have been friends since freshman year of school, so 10+ years. When we initially met, there was some flirting going on but nothing ever really came of it and we both started dating other people. So, not a big deal.

Once we graduated, we kinda drifted apart as most people do but still kept in touch from time to time. But for the last two years, it's been down to me wishing him a happy birthday. Literally in our chat was me saying happy birthday last year, him thanking me and me asking him how he's been. He left me on read for the year. Yesterday was his birthday so I again wished him a happy birthday. He read it and hasn't said anything. Not a huge deal normally, I get that people are busy and especially on their birthdays, are inundated with messages. But you can't even send a smiley? To someone you've known for 12 years? 

John and I used to be super close and yes we have drifted apart as adults but the lack of communication is just annoying. I've made a rule with myself to only have people on Facebook who I truly talk to and are active in each other's lives. He's made it obvious that Im no longer a part of his life.

So would I be the asshole to just remove him from my friends list?
