Hi - me too!
Making friends is the one thing I feel a real failure at since I had my two - now six and nearly two.
I'm 39 and gave up work when I had my second daughter. DH has really struggled to find work since (he was a house-husband for four years with DD #1) and has been doing contract work, which is scaryily unrealiable moneywise and he gets annoyed. I think he feels a bit of a failure, which he is not, he just really wants to get back into a career.
There were a couple of mums DH was chummy with when he was at home, but we just haven't gelled (it doesn't help that when I see them out and about, they just want to reminisce about what a great time they had with my husband! )
I tried with the school-run mums, but they seem either too cliquey or I just don't like them. I still see an old school friend every six months or more, but she is onto pregnancy no. 4, lives many miles away and I don't have a car (I can't afford one).
I'd love to think that one day soon I'll meet someone I really get along with, who I won't get bored or irriated by and who likes my kids and DH too !!!!
I do try to be nice and chat to everyone in social situations but I have become a bit paranoid sometimes - worrying that everyone hates me even though I don't actually want to be friends with them
Is there an answer, except to keep on going?!
