No sh*t, he has a f*cking girlfriend. But if you actually absorbed the information in my paragraph above you would realise that that was not my issue nor why I am grumpy.
Means he doesn't f*cking want you.
So you told a straight guy, with a girlfriend that you have a thing for him?
Why the f*ck would you do that? Seriously, sure holding back might suck for you a bit, but telling him is just going to make it weird and it's going to suck for both of you, even more than it sucked it the first place, I wouldn't mind that much, but your friend obviously does.
Some things you don't tell people, ie: If a girl has a fatass, you don't tell her that.
Anyway, related to that, a girl I've known and been good friends with for a long time came out and told me she has a thing for me, this happens right after I tell her she's just a friend and I'm not interested, and conveniently right after I get a new girlfriend.
Seriously, chicks only want what they cannot have, I was trying to get this girl years ago and she wasn't interested, but suddenly when I'm not up for grabs she's over me like flies on a stick of honey.
