Being mono isn't a problem, and meeting her certainly won't change that. You know that right?
I sense that there is something underlying your fear/concern. But I'm not catching what it is.
I know that for GG (my boyfriend), he's mono-but he's very secure in our relationship and enjoys meeting people in my life.
On the otherhand, Maca (my husband) is poly and he's so insecure that he can barely handle dealing with GG....
I'm still very curious as to exactly what it is about meeting her that upsets you. If it's THEM and the affection-it seems an easy solution to meet with her when he's not there.
Is it maybe somethign else?
