Nah, I've certainly had a few reflective moments where I realized my missed opportunities. The reality is, unless you're really confident and self-possessed, it's hard to put yourself out there. So I can understand why these guys didn't just spell it out for me, cause they likely weren't sure I was into them. And on my end, I always struggled with low self-esteem, so I just assumed that these attractive guys weren't actually into me and were just being nice/good friends.

Anyways, I'm glad your girlfriend is an exception to the rule.
