<human>: I (23 F) work in a research lab at a university, and there's a guy (23?) who works for the same lab, but I only tend to see him 2-3 times a year. Recently, we had to meet alone to edit a paper we're publishing together, and I found that I was getting giddy, excited, flushed, all the signs that you're attracted to someone. He laughed really hard at casual comments I made, conversation flowed really easy instantly, and I could tell there was mild attraction.

I felt SO GUILTY with every giggle and butterfly I felt. I would giggle like a schoolgirl and then instantly feel guilty inside. I've been dating my boyfriend (25M) for 2.5 years and I'm incredibly happy with him. I barely know this new guy, and I have no idea if I would end up happy, heartbroken, or furious if I dated him for 2.5 years. I know from 2.5 years of experience that me and my boyfriend are a great match.

I don't intend on increasing how often I see this new guy, but I will likely have to have meetings with him once every while. Is it okay that I feel so attracted to him? I can't control it! I try so hard to be "chill" around the guy, but it's difficult. I've told my boyfriend and he laughed and told me it's normal, just don't get romantically or physically involved with him.

I feel so guilty. How do I stop feeling so giddy around this guy, or how do I stop feeling guilty about it?

Can you provide a brief overview of the text?
<bot>: Publishing a paper with a hot dude and I get the butterflies around him, even though I'm in a relationship. Is this acceptable? If it's not, how do I stop?
