<human>: Can you condense the text into a few key points?

I crave attention.

I never really got too much of it as a kid, so it's something that I subconsciously seek out.

Unfortunately, that means I immediately fall in love with any relatively attractive girl that shows even the tiniest bit of interest in me. 

These crushes don't last a long time.. a week at most. But during that week, I'm in full on crush mode. I start to sweat if the chick starts talking to me, I get about a million butterflies, my throat starts to close up a little bit, and I get extremely sad if the chick doesn't talk to me that day. It gets to a point where these weeks start to become pretty painful because I start thinking "she's not talking to me because I'm not good enough".

All of this causes me massive, massive guilt. I love my girlfriend like nothing else, and nothing would ever cause me to cheat on her or leave her.. yet for some reason, I can't help but have a huge crush other chicks for a week at a time (give or take a few days). 

What do I do? Should I talk to my girlfriend about it? Should I just accept that that's part of me? Should I just try to suppress the emotions?
<bot>: I fall in love with every girl that looks at me, and the guilt is killing me because I love my girlfriend of 3 years to bit. What should I do?
