Polyamory

Hi, Sorry I don't know if this is the right place to come, to but I figured you would all have a much better understanding and be able to help. My partner is poly, but I'm not, and I'm really struggling with her seeing other people. I don't want to lose her, because she really is the love of my life, and we just connect on a higher level. But I know seeing others makes her happy. I just need some help navigating, because this is all very new to me, and I don't know what to do to help us work as a couple.
