I'm in the same boat as you all. I would love to make more friends, and am going to invite one of the girls from my M & T group over for coffee when I see her tomorrow. This is a big step for me, as I have been hurt by supposed friends before, so I am wary of rejection.
I have three friends who have babies, and I see each of them about once a month. One of them is a fairly new friend, and I am trying not to get too 'involved' too quickly, and to let the friendship grow naturally. We have reached the stage where we are tentatively confiding the less important dh stories and moans to each other, but no deep dark secrets yet! Of the other two, one is a long term friend who I would trust, and who I know a deep dark secret about! The other is an old friend, but we have only recently got back in touch with each other, so again, I am taking that one easy.
I always seem to come into contact with people who make friends easily, and who have tonnes of friends, and this makes me feel very inadequate. Sometimes though, I think that these people don't try too hard, and this is what is attractive to other people. My early relationship with my mum made me very eager to please everybody, and I think that this can come across as depreation, and scare potential friends away! Coupled with on/off depression, I am probably a friendship from Hell!
At the next meet-up, I am determined to come. I did not attend the Xmas one, through lack of courage, and fear of losing my anonymity.
