Lynne I am a bit like that at times too... My closest friends are not married and don't have kids. I've got one friend with a one year old but don't see her very often, and my friends without kids have done a few meet ups recently (trips to clubs etc) without me. I think it's partly my fault as when we were having no luck ttc I think I pulled away from people a bit. Then we moved in may and while its only half an hour away from where we were before, it makes seeing people that much harder.
I'm still seeing a few friends once/twice a month but that's about it.
Hopefully we will make some new mummy friends a antenatal classes etc! Xxx
