Hinge and I, the Secondary Partner, have said I love you
This is my first experience with poly relationships; hinge has been practising poly for about 2 years, I've been doing it for 3 months.
Meta (hinge's primary) adores me and is very supportive of our relationship, though naturally sometimes feels jealousy - but they and hinge deal with it and work through it on their own.
I've been told by them that I have really great instincts around how to behave in a poly relationship, am very respectful of their relationship, am great at communicating and so on.
But even so, poly for me is untreaded territory, and loving your secondary is untreaded territory for hinge. Hinge and I are looking to go on a trip together soon.
Any advice? Please be kind, I'm new to all of this!
