I have 2 girlfriends in a polyamorous relationship. I have been dating the first one for a couple of years and I recently started dating the second one for 8 months. They are friends with each other and have we all enjoy each others company and intimacy. I love both of them, and for the last couple of months I've been extremely happy. Unfortunately, both of them want a conventional marriage. I come from East Africa, polyamorous relationships are very out of the norm.
A conventional marriage to either of them would likely hurt and make me lose the other. I'm happy with both, and I don't want to choose between them. Any ideas on how other polyamourous relationships do it?
How do I set a conversation to make a case on how we can all be happy without the conventional marriage in a way that none of them feels less than the other?
