I met my ex-husband in a bank.
My girlfriend and I were using the same forum, which is not poly or dating related. We noticed each others writings, met face to face as friends and it developed from there. We were both in open relationships when we met and that's how our poly life started, after dicussions with our other partners things got serious quite quickly.
My FWB was originally a friend of a friend.
Me: bi female in my 30's
Living with Dahlia and Eddie (friends)
