I don't know how common it is, but here's some advice: I've on and off been attracted to a lot of women, many of whom I managed to resist for whatever reason. (Dating someone else, awful person, they weren't attracted to me.) You know what? I didn't accidentally ravage any of these women, nor did my pecker fall off, nor did I embarrass myself. So don't worry, I'm sure you'll be all right too. You're making it too complicated. Feelings can't victimize you if you don't let them. You don't really want her so you don't hit on her. Or, you decide your feelings are valid and you do hit on her. It's really up to you. You seem to think your feelings are going to sabotage you somehow. Do you not have a will? You can't get rid of your feelings, but you should be able to not act on them if you wish. The feelings will go away in time on their own. At worst, they'll go away when she does after study group is done.
