Your minds already made up. I gaurantee you'll be back with her. I will put money on it. Your gonna go on your trip and everything will seem great because your on vacation and a month after you get back you'll be unhappy again but you won't leave her then. You'll wait another miserable 6 months and then grow the balls to do it. At that time you'll come back here and create another thread exactly like this one.
There's your future bro and you didn't even have to call a 900 number to get it.
