When I first split with xp I was expecting the looks, the comments etc, but I really haven't found that at all.
He was never really around much anyway (he was here, but was too stoned/interested in his mates to bother with us), so I was often out with the boys on my own anyway.
I've recently got back in contact with a lot of old friends that I had drifted away from over the years (one in particular that I actually emailed & told her I no longer wanted to be friends with ).
I'm also a lot more confident than I was a year ago, and can now strike up conversations with random people when I'm out which I never would have done before.
Maybe I'm going off on a tangent here, but what I think I'm trying to say is that since splitting I've got more friends, speak to strangers a lot more easily & have really never found anyone looking down on me because I'm a single parent. I think that is because of my outlook on it, I'm happy, confident, my children are happy & (when in public!!!) brilliantly behaved.
At ds1's old school, I was actually the only single parent in the whole year (it was only a small school, but of 22 children, he was the only one from a single parent family) adn didn't find that difficult at all.
