It's evidence that makes me, and many on this thread, recognise these patterns. We're not going into it expecting it, we've discovered it to be the case, over and over - sometimes years later the realisation dawns; or, in the case of the people who didn't turn up to my party, decades later. Also the sudden cessation of mutual childcare - which I put down to allsorts, for years not being able to fathom why it had happened.
It still surprises me. I still don't see it coming and each time I find it confusing as I don't expect it. Why would I? It makes no sense.
I feel rather pissed off that people seem to be posting who haven't experienced this firsthand but assume they're knowledgeable because of what they've seen. eg you don't ask a white person if an area/town is racist, you ask a black/non-white person. Yous who are insisting singles are not marginalised, ask your single friends how it is for them, not how you think it is for them. yy some of you may get the answer you're expecting (eg grand) but this is unusual. It is not the norm.
The spas etc stuff has been covered, Aggie: op has acknowledged she expressed herself clumsily. But I'll stick my neck out here and say my experiences were that spas were a right of passage at the time I experienced conclusive and clear marginalisation from women groups. It's true I don't like spas - can't think of anything worse tbf - etc but my experiences of trying to get in with women in my social group were entirely frustrated - sometimes because I didn't have the money to go to like spas but mostly because they couldn't figure out who I was, what I stood for, because I didn't have a partner. They couldn't relate to me, in short. Their response to me was very clear that they considered me - what I did, and didn't, stand for - a threat. Possibly a passive threat ie they didn't know why I was suddenly 'out', were not self-aware enough to acknowledge they treated me differently. I can say that in hindsight but at the time I couldn't work out what was going on - of course I took it that I just wasn't likeable and agonised about what about me wasn't likeable; what was I getting wrong? I had been popular and well-liked when I was in a couple but it took me a long time to see that, to see that things changed dramatically when I became single. BECAUSE I became single, more to the point: I was suddenly out, suddenly non-U.
