For the last 8/9 years I've been living back in my old university town, and had a healthy group of friends - a mix of old uni friends, new hobby friends and people from work. I'd say there was a regular group of 8 I could reliably meet up with either separately or together. Mutual degrees of inviting.
I am currently 7 months pregnant (so probably pretty hormonal). I have noticed over the last 4/5 months I have been doing all the contacting, and in the last month I felt a bit insecure so I stopped to see if others would contact me.
I've not had one invite in that time, it feels worse as we just had such a sunny weekend, I spent it doing nice things and have a lovely DH but I could hear people laughing with friends in their gardens and felt quite sad.
We're all mid/late 30s, nobody else with children or married but we've always enjoyed the same things. I wondered if it's because I'm pregnant somehow but I still don't understand? Is this it now?
