Nothing is stopping those men from changing their wardrobe, or appearance. Nobody deserves a medal for not putting effort into their appearance. When women can’t find a man, they are told to lose weight, dress better, learn how to properly do makeup, etc, so the same can be said for men. Looks matter. Period.
Were those guys into the books trying to get with women who were into the books, or were they expecting attractive women to approach them? And like I said, once you start dressing better, and looking better, you have access to new women. A lot of those guys aren’t going to stick with the woman who made them dress better.
