Maybe this is unusual - I’m still in touch with an ex’s family and have even been to their thanksgivings, even in periods where my friendship with my ex was in a rocky place lol. They’re just awesome people and I genuinely like them. Not once in the 7-8 years since we’ve broken up have they mentioned anything about the possibility of us getting back together, or wishing we would, or anything like that. It can happen! But maybe not often lol.
