Way weigh whey too emotionally invested in this woman (probably women in general too), and you two weren't even married. You weren't dating this chick a full year either! I'd urge you to tattoo "nevr" on one set of knuckles, "agan" on the other set, but not only would it be entirely unaesthetic and unpleasing to the eye (in my view at least), it'd be belaboring a point I'm confident you'll understand with time well-spent browsing this forum here extensively (beginning with this very thread, I'd suggest).
Women cannot get under your skin the way that this one did - ever. Self-injury on account of a woman's fickle nature??? What's next? You punch the girl? Destroy public property? Get behind the wheel after chugging a twelve pack? You're emotionally out of shape. That can be fixed, and it will, provided you will yourself toward emotional fitness. I wouldn't go looking for another girl (just yet) if I were you. Take a break from women for a bit (they aren't going anywhere) and put things into perspective. Are you as determined about seeing your goals in life come to fruition as you were about making things "work" with this girl? Why was it so important to make it work with her to begin with? What made this one so special?
Like I wrote above: comb through this thread for more perspectives from different posters, more wisdom, more inspiration, the feeling of solidarity, DO NOT contact this girl under any circumstances (consider her dead from this point onward), and read this carefully here to begin reprogramming yourself -
