S.K.
There is a Moms group in Mansfield. it is on meetup.com It may say closed to new members but I think you can e-mail to Michelle and ask to be included. They are a really nice group of Moms.
There is also an Arlington Moms group. There was a lot of drama in that group and then they split into two groups. I stayed in that for a while but didn't really like the vibe. kind of clique-ish to me.
i live on the mansfield, arlington, grand prairie border. The Mansfield Moms group have lots of fun activities all the time. I think you would like it.
