He has a girlfriend. Why does he get nervous around me?

[Anonymous]

I like a guy at work. It seems as though he likes me too. It blew my mind to find out he has a very serious girlfriend. While I'm picking my little heart off the floor and exercising my boundaries I've noticed nothing has really changed. We've only gotten more awkward around each other. Especially when we are alone. He will watch me or ask me to stick around to be involved in stuff. But when we are alone he gets weird almost nervous. I mean I know why I'm weird I'm trying not to like him and I'm single. However he isn't. My question is... he is in a serious relationship, why is he getting nervous around me?

Its because he likes you... but you both need to set boundaries. Don't go for someone whose taken. What he does to her he may do to you..

I'm trying not to like him. I don't want someone else's guy.

You guys should talk about it or avoid him but avoiding someone isn't nice

I want to talk about it but I'm pretty sure that will make things worse. The tension is already thick. And I see him trying to do the right thing. At least that's what it looks like.

Avoid him. If he's willing to cheat on his girlfriend, then he's willing to cheat on you

I don't think he is that kind of guy and I'm definitely not that kind of girl. I believe in karma.
