Notwithstanding john's excellent advice, there is a thread about jealousy in relationships here.
It's in the sex threads, but it's mostly talking about relationships and jealousy that arises from that. You'd probably get more of a response if you repost over there.
Generally, we try not to start new threads if there is an existing thread your question can fit into; I know BUST is sort of unique in that regard to other message boards.
You can check about new threads and find out where to post your queries here.
I saw over in Newbies that you grew up in Buffalo. I'm from Rochester, originally. Howdy neighbor, and welcome to BUST!
