<human>: Could you distill the essence of the text into 1-3 sentences?

I feel so stupid posting this because it's such a silly problem, but it's a problem nonetheless.  I can't help but get jealous at my girlfriend's celebrity crushes.  It's not like she is constantly talking about them or something, but if she mentions something like "oh I love him, he's so hot!" I can't help but feel pings of jealousy, and then I shut down and am cold towards her. 

It's completely stupid and irrational, but it still makes me feel terrible.  I've been cheated on and left in the past for other people by ex's, and I think it sort of taps into that.  How do i not let it bother me so much?  A little comment sadly can completely wreck my mood.
<bot>: I get jealous over my girlfriend's celebrity crushes.  It taps into the feelings I felt when I was cheated on/left for other people in the past.  It's ridiculous but I'm not sure how to not care...
