ugly head

I don't know that I'm a really jealous person. I mean, I don't think I'm any more or any less jealous than the next person, despite my insecurities. Jealousy is such a strange thing at any rate, you never know when it's going to strike or who will inspire it for that matter. I got jealous last night. If you've been following this blog, you'll remember that I chased my fella for a while and one time witnessed him making out with some girl...who he then went on a few dates with and at some point she decided she didn't want to continue whatever it was they were doing. But recently, she's come back and has been emailing him and wanting to "hang out" again...as friends of course (picture skeptical raised eyebrow and lip raising). And I guess he said yes, they could hang out as friends (picture completely raised eyebrows and mouth in a tight little grimace). And I am a little upset and jealous about it. Actually, I think it's a little disrespectful, which is the main motivation for my jealousy and feeling upset. I don't have any issues with his other relationships with people of the female variety, but this situation is maddening. And I don't know how to deal with it...or with myself for having these feelings.
