I’ve seen some articles that address the issue of single women at age 32 or so who live alone. You’d be surprised how few of them percentage wise go on to get married after that. I will say that more women are waiting later in life to get married.
So yes you are right. It’s not the virginity issue. It’s the issue of her simply not making connections.
While you may be right in attributing it to her being stupid and looking for the wrong kind of guys, the dynamic still plays out for these and I’m sure other reasons.
You are so better than this.
