Welcome to our forum.
You might enjoy posting on our Life stories and blogs board
, it will give you a chance to tell your story in detail. Also I would do some posting on some of our other boards, it will give you an opportunity to meet some new friends and get their input and advice.
It sounds like you have experienced polyamory, and didn't even realize that's what it was called. So, now you have a place on Polyamory.com, and an opportunity to learn the ins and outs and what has worked for other people.
Glad you could join us.
