My girlfriend and I have been dating for a little over a year and a half. I'm poly and she is to the point that she will do it for me because she loves me.
Over the past few months an intimate relationship has developed between myself and another girl, whom I've known for about a year now, that my girlfriend cannot stand.
I have developed very deep affections towards this other girl despite my girlfriends dislike. I care for them both deeply, but my girlfriend cannot tolerate to be around this other girl.
How do you deal with loving two people when one can't stand the other?
