I think there is a basic type of person who thinks ''at least I'm not single like her'' the type of person who stays in a meh relationship with a very very ordinary partner. They don't realise, the people that they feel ''at least I'm not single like her'' about, those people were strong enough to say not for me, walk away, call time, sit comfortably in their own company, go places without a sidekick.....
I feel brave, and proud of myself. Apart from a disastrous relationship with my children's father and a few short relationships (some fun, some awful) I've been single pretty much my whole adult life. If anybody looks down on me then they have a limited understanding of how you grow as a single person, imo.
Saying that though, I do feel bullied and gaslighted by my mother and I do not think she would try and FORCE her distorted narratives on me if I were with a strong partner. I was with somebody who was strong and succinct and didn't get upset or unpleasant when he was fighting his corner, if he'd been a long time partner or husband, my mother wouldn't have dared to try and gaslight me the way she has. There would have been a very strong witness to her antics. As it's just me, my mother has gaslighted me for her convenience. But, I digress. Although, my mother is exactly the type of person who feels sorry for me being single. So it is connected.
