Thats fucking awful, I'm sorry dude. Time is the only thing that is going to help you now. Everything is going to be shitty for a while but eventually it WILL be better, I assure you. Just be thankful that you didn't marry her, now you know her true personality
thanks man, i really need that. I'm now all alone in a big city with no family nearby, 2 bucks to my name and an apartment full of her shit and memories.
Your profile doesn't say how old you are, so I'm assuming you're in early-mid 20's. Either way, the both of you are WAY too young to be getting married anyway. Believe me, this is life's way of letting you dodge a major bullet.
