I have always wondered why girls always wonder that guys are fearful to approach them. A lot of times my biggest thing is wondering what to say and making an approach. The fear of rejection is always a big thing for me, despite it being something I should be used to (since I always get rejected for the most part). It doesn't hurt less, it hurts just the same and maybe even more especially since I am getting older. Especially since I am not someone whose a big talker, and bad at conversing in general it is a very daunting task for me. So yeah there will always be that fear of rejection present, and knowing that there is something about you she doesn't like. Also it is hard to see what you're doing wrong since, the girls I have dated never told me why they rejected me.
