HUGS my dilly sisa!

I am so sorry to hear your having some dificulties there. It can be really hard to find compatable people in r/l and sometimes when we even get close, we can get very clingy and dont wish to end things.

I reccomend you re-read your post. I think you allready know whats right for you.

I see no reason why you cant remain friends with the submissive, but I would keep in mind that that dominant sounds like he is full of alterior motivations.

The only times poly has worked for me for any length of time was when ALL parties knew the score and agreed upfront by mutual 100% consensus to be cool, and even then sometimes there were complications later.

I wish you the best of luck!
