Hi breezely14,
I went searching for a forum that would help and there is just not much available. There are some books you can read. I would suggest counseling as the best option.
This book has been helpful to a lot of us for our different problems. I think it would be helpful.

I know jealousy is extremely painful and hard to overcome. I'm sorry you are experiencing those painful emotions.
I think Co-Dependents Anonymous would also be helpful.
