<human>: Can you give me a shortened version of the text?

I am happily married, have been for a few years, however I think I have a crush on my co-worker.  My co-worker [lets call him Dave], is usually the one to talk to me first.  And he can be a bit.. flirty? He knows I'm married, and the flirting is just playful flirting. He has never blatantly made a move on me, and I have never reciprocated in any flirting.  Even if my husband weren't in the picture, I could never see myself with Dave as we have too many fundamental differences. Is it normal for me to find myself thinking about Dave? Is it normal for me to wonder if he thinks of me?

Just to clarify, I would never cheat on my husband and always feel incredibly guilty of even remotely having a crush on Dave. In fact, over the past few months, I've distanced myself from Dave and tried to maintain no-contact in an effort to get over the crush.

My husband is everything I ever wanted in a partner, we never fight, the sex is great, and we are each others best friends. So why do I have a crush on my co-worker??
<bot>: Happily married to a husband who is perfect, is it normal to have a crush? How can I get over it?
