Went to a baby group. Was invited there by health visitor as she said it was a great opportunity to meet mums and young babies who live nearby.
After the introductions and topic of the day discussion run by health visitor we had a informal time for chatting. Chatted to a couple of mums sat nearby. Small talk about sleep, naps, pram walks, baby ages/names, baby clothing size etc.
Then I was chatting to one mum and I mentioned that I was looking forward to going to the local cinema that runs baby and parent movie sessions. I said I went to one film before I had my baby when I started maternity leave and it seemed a really busy social experience, lots of mums and babies chatting in the foyer beforehand etc. she replied ' no I don't need to do that sort of thing as I have a lot of sisters and sisters in law and their children close by for company.' I felt embarrassed as it felt like the cliched excuse/ rejection line 'sorry I have a boyfriend' 

What do you think? Would like some opinions as feel a little self conscious about talking to other mums now.
Just to add I don't have any family nearby but I do have a few friends, including those with children so don't feel completely isolated but am open meeting other mums who live nearby.
