I’ll be honest, we’ve never had any friendships really and we aren’t interested in having them either.
i have a best friend that I’ve had since childhood, I see her and her son on my own, although my partner has met her, we don’t all mix together.
my partner has a couple of friends that he sees every now and again, without me, although I have met them too.
we also occasionally go out with my partner’s sister (she’s a similar age to us) to events.
and that’s it. We’ve both been hurt badly in the past by our respective friends/friendship groups (before we met each other) and neither of us is fussed about having anymore. We don’t feel like we are missing anything.
Sorry, I know that’s not helpful, it’s just different things for different people I guess! I think this is part of the reason we aren’t fussed about having kids, A) we don’t have anyone around us with kids and B) we don’t really have a big support network so we are used to being just the two of us.
