Why am I so jealuos?

That's something only you can answer. You are the one knowing yourself the best. :rolleyes:

It is generally due to low self esteem. Or perhaps you have cheated on someone in the past...

Can you give us some more details please?

You don't HAVE to be.

What are you jealous of?

A lot more details are needed. What are you jealous of would be the biggest key clue!
