Yes, but not enough. I have 2 old friends that I meet up with every few months. My longest friendship is 20 years and I'm 46. I do feel a bit sad that I dont have school or university friends. I also have about 10 local friends made since having the DCs but they're joined friends with DH and generally I would say they're not that close.
I have to say I do find alot of people are not that nice though.
Maybe I'm at fault for being too choosy, I dont know. But I have learnt to avoid groups as I seem to have worse experiences then.
We were part of one group when the DCs were young and TBH it just always felt very competitive. All they talked about was schools and house extensions. 
we decided to give them a bit of a wide berth but it doesnt stop it stinging when I see their NYE party photos all over SM. Even moreso given one of the reasons we stepped back was the constant bitching going on. I sometimes wonder if I cut my nose off to spite my face, but I really struggle with the fakeness of friendship which seems to be necessary in all but the closest of friendships.
I'm really doubting my self at the moment as I also had a bit of a bad time with a group of mums at the DCs school. They used to go for weekly coffee and as I'm not working on that day, so I was invited a few times. Then suddenly the invites stopped and it all felt a bit awkward. Then I bumped into them all sat together in a local restaurant, but I honestly thought nothing of it but I could tell by all the glances that they felt weird about it. I have no idea what I did wrong and that's the worse bit. I often just seem to get it wrong in social situations but I dont know how to fix it. 
I generally dont stay in touch with ex colleagues , and I find it very hard to socialise in big groups but I have also learnt that the intensity of one to one meet ups is sometimes too much.
I have a friend who is extremely popular and has friends all over the place. We both turned 40 in the same week and I was so embarrassed when I compared my celebrations to hers. She had a huge party with about 100 people who travelled far and wide and cards all over her house. I had 5 cards (3 were from family ) and even if I had wanted a party, it would have been embarrassingly small. I dont enjoy parties anyway so not the end of the world. But even my 'best' friend made very little effort for my 40th despite the fact I organised a night out to a lovely restaurant for hers.
I find people often take advantage of me. I like to think I'm kind ,I dont bitch and I'm always happy to help. But I have lost count of the number of playdates or sleepovers I've hosted and never been reciprocated. The same for having people over for dinner. Dh and I will cook lovely meals ,provide wine etc and often there is no return invite. I always return favours, but it feels like most folks think take, take, take.
The bottom line is I am the common denominator. I don't know what I do to put people off but I just do. I hear people talk about their uni friends or how they went away somewhere, what a great pal someone is or see them meeting up in groups after the school run and I feel like there's this invisible wall that I can't climb over. I would love several nice friends who would text me,pop by for coffee and wouldn't end up using me or bitching or just being weird in some way ,but it just doesn't happen. One of my new years resolutions is to try and sort it out and be more sociable. But along with that I feel I need to accept I have introverted tendencies and enjoy my own company.
