Single parents and social life/friends

[MrsAnonymousYummyMummy]

So I am a single mum to a 4 year old and my social life is work (small place, and only chit chat) and gym 3 x a week. I have 4 friends but they are all married with kids and mostly busy with them. My stbxh has our ds one night a week on the weekend but I struggle to find anyone to do something with. I also take my son places on the weekend and find it hard around all happy families and I'm on my own. Where can I find some single friends or better still single friends with children? I have looked into gingerbread and they have nothing in my area. I talk to a couple people in my gym, one girl is a personal trainer, similar age to me, is single and quite friendly but she is chatty to everyone. How could I gauge if she would be interested in meeting up outside of gym? There is no-one in my work who I could socialise with, most people are either a lot younger than me or a lot older, and most have long term partners, also live quite distance from me.
Any ideas gratefully received :)

Have a look on //www.meetup.com

There may be some stuff going on in your area

I find that my hobby, music, is a good way to meet like-minded people. Not necessarily with children but it seems to have worked out OK. If you like the gym do you enjoy team sports, for example?

Is there a local gingerbread group in your area? We used to go when we lived in another area and really enjoyed it. You can go on their website and use interactive map to find out if there is.

Take an evening course? Thought that can be difficult with babysitting can't it.

You could just ask the PT if she knows anything good on at the weekend as you have a sitter and no plans? It's worth a go.

Also Facebook sometimes has some local lone parents groups.
