I have been a single mum (my partner died) for some years now. Have a number of friends who I've known for 30 years, who are married, ie have joint salaries, and are increasingly enjoying holidays together as couples, and I just can't keep up. We are still friends, in that we still meet up, but I'm just feeling so low and bitter. It's not their fault that my kids' dad died, but it's not my fault either. We've all been friends for so long, but I feel I'm being phased out, for being 'inconvenient.' Can anyone relate?
