I wish I had a better answer for this.. I don't manage emotions very well and I have a tendency to either get very attached very quickly or completely detach myself emotionally once someone starts also showing emotional attachment. Ugh. I'm struggling very hard right now with an attachment to someone whos emotionally committed to their partner. I also find myself getting attached to people who I know are either incapable or don't want any sort of real relationship, and I'm not even sure that I'm capable or want that either. It also doesn't help that I struggle with pretty bad depression, anxiety, and a tendency to cope with those by drinking/drugs/etc. I do think there is a way to bridge monogamy and polyamory in a way that works specifically for those people.. and that you won't really know what that is without trial and error and probably some hurt feelings along the way.
