Quality!

I'm a bit over being the jealous type. In fact I hate it. It is a quality I certainly don't like in other people but I especially dislike it in myself.... as long as I can remember it's always been there.

I'm not a overbearingly jealous person and I'd say that most people wouldn't even notice or have any idea that it's a quality I'd even possess, but it is always there. Somewhere along the line I've been someone's favourite at something and I've turned around and reckoned it's rad.
It colours the things I say, every now and then I will totally launch into and tease someone that's funnier than me, every now and then I find myself asking Cara questions to find if I have a reason to be jealous. Even though I'm probably subtle, she's a chick and clearly picks up on it. Picking up on it colours the things that she might tell me, which means I notice absences or stories that might not match up or people might say things that she probably should have.
Understand, that I'm not even talking about important things, I'm not talking about Cara cheating or even being outrageously flirtatious or anything. The things I get jealous over are so stupid that I when I wake up I feel silly and childish. Even though she's cluely, I'm sure that even she has no idea about all the things I've been jealous over in the past, I'm smart enough to (mostly) think before I speak.

Anyway, how do I fix this? How do I totally learn that I don't have to be everyone's favourite or even that if a girlfriend did cheat on me, or love someone else or whatever, it'll be crap but then it'll be fine. I know I can deal with anything, I just don't know why spikes of jealousy pepper my conversations.

It's a self-respect thing I'm sure, where do I buy one of those?

P.S) Yo! It was salsa dancing I think, hell, I don't even know. How many salsa sauce conventions are there?
