I am super friendly. And am friends with a bunch of guys who work next door. I recently found out one of the guys I say hi to has a girlfriend. And soon after me finding out, he has started ignoring me? I was never flirty with him, but enjoyed saying hello (as I do to them all) today I walked in and said hi. He didn't even look at me. His buddy said hi but the other one acted as if I wasn't there. What's going on? I'm so sad, as it makes my day conversing with them all. They are all such nice people to be around. Just to add, I never flirted with this guy. Everyone gets the same amount of conversation from me.
