I don't have many friends, I'm in my 20s not that it makes any difference IMO. I don't really have any very best friends and I always feel like I'm way more into people than they are me, so then I don't want to look desperate. I always suggest meet ups etc then leave the ball in that person's court, and then when they don't reply at least you know they're not into getting to know you and you can try another person down another avenue!
I have 2 mum-friends I met through a lot of tenacity at baby groups. They both seem to have a lot of other friends but the 3 of us are all local so we see each other a lot. Not sure how deep the friendship is but we go out for dinner every now and then and it's really great actually.
Another mum friend is someone who is just a lovely lovely kind social butterfly and lovely to everyone and makes time for everyone, so I'm very pleased to know her, but not someone I'd class as a close friend.
My 'best friend' is my childhood best friend, don't see her often.
Another 'friend' from an old workplace but we're both a bit flaky with each other and lead very different lives, kind of just keep in touch and meet up with the kids sometimes.
My only other friend is my cousin! Who I love but can never pin her down to get together, I think I'm keener than her.
I managed to join a group of 'Local Ladies' through a pregnancy app and we've met up and have another meet up coming up(really not like my, way out of my comfort zone!), they all seem lovely and very promising! Hopefully we'll stay in touch once the babies are born. Likewise I have an NCT class starting next month.
DH is my absolute best friend, I get that people might think that's sad and what happens if we break up, but I think that is not going to happen. It's like the SAHM debate, I'm not going to live in fear of my marriage crumbling! That would be a big warning sign that the marriage was not good in the first place.
I've tried apps like Peanut, Mush etc, met one lady from Mush and she was nice to my face but I clearly didn't fit her acceptable friend mold - saw her at the park a couple of months later with a group of friends she'd found, all carbon copies of each other, willowy, blonde hair and boden which is so not me! So there we go. That's fine, she seemed happy!
