Whatever. Why would you even trip? He's not all that anyway. First of all why even continue to text him?
Don't use Facebook to meet guys, okay? It's the same as online dating-weirdos and freaks mostly. If you look anywehere near desent, I'm sure you can meet men to date in IRL too somewhere. Like texting someone for month and months doesn't really make a relationship, does it? Don't put yourself in these types of situations anymore. Doesn't matter if he's moving, let him.
