Oh gosh, this is a big train wreck already. So yeah, go ahead and just tell the other girl. See where that gets you. May as well accelerate the fall to rock bottom, come to some self-realization, and then you can finally move on.
Logically, I'd say either have your vision checked, or examine the sights, maybe practice your aim, and if that all doesn't work, invest in a scope. If you can improve on any of those counts, then you'll hardly be missing anybody in no time.
About plaid, I don't know. I can't recall a time when I've seen a woman wearing plaid for some reason. All I can say is that I don't think I would dislike it. I guess it depends on how well the particular woman pulls off wearing that style. *shrugs* As for noses, I'd have to say that in general, I prefer a higher nose tip (as you've described it). Unfortunately, I hate to say that I don't particularly find flat noses attractive.
But be careful oh how intense you decide to make this cleanse. You only want to do it just enough to forget about him - but not so much that you also forget that you have a job that you need to do to pay your bills. If you end up doing the latter you might end up becoming ... uh... a hermit.
^ Mmmm..that was rather frustrating to read. But I can't help but also feel that you could have just interjected at some point early when it started getting out of hand that you and Jason were "pretty much decided on doing either ramen or vegan at these specific places and just thought you might have time to hook up with us. But if you can't, you can't ...." I don't know, something along those lines. *shrug*
(It's reading anecdotes like these where I sometimes relish being a hermit and just eating by my own damn self, on my own time, and where ever I damn well want.LOL)
Are you asking literally or just figuratively? Because I had a love interest that broke up with me by running me over with her car. Given the circumstances, I was easily 'over' her relatively quick. But I didn't heal from it for about 6 months because I was in traction most of that time.
