A lot of the comments here mention looks, and how looks might fade or not with age. Surely, guys fall for women with looks. However, where guys really go "all in" with time, money, attention, etc., is when a guy thinks a woman is going to bear his children. Even if a 36-year-old BPD women is looking hot, she's simply not going to get away with some of the over-the-top BPD behavior she got away with when she was 28, for example. I think a lot of high-caliber guys treat hot 36-year-olds as one-night stand targets, not as candidates for an engagement ring.
Wow. You do realize that a lot of people on these boards are women, and not all of us are in our 20s, right? And that this kind of talk is very objectifying?
