Might I suggest that you may be looking at this all wrong- women are more attracted to your confidence than your looks. I suspect that your physical attractiveness is just fine, but the event of being dumped by this smart and beautiful woman hurt your self-confidence, and caused you to seem less attractive to other women afterwards.
The sort of guy who thinks a girl broke up with him because of his unattractiveness is very unattractive to most women, whereas the sort of guy who thinks "it's her loss, I was out of her league anyways" is highly attractive. If you get (or learn to fake) more self confidence, I predict that your success will return. Ironically, being arrogant about how good you are is both necessary and almost sufficient to actually be good.
I don't mean attractiveness just in the sense of physical looks. I mean the whole thing of my social standing, confidence and perceived coolness.
But thanks for the advice.
Admitting to being wrong isn't easy, but it's something we want to encourage.
So ... were you convinced by someone's arguments lately? Did you realize a heated disagreement was actually a misunderstanding? Here's the place to talk about it!
