Time to unplug, Molly.
You haven't met this person, therefore you DON'T know him, all you have is what he's told/texted you, which may or may not be true. I wish I could clearly express to you how ridiculous (and potentially hazardous) it is for someone you never met to declare they "love" you, particularly as young as you are. They only love what they imagine about you. Pretty desperate stuff. This nonsense is how young girls get missing.
Be straight with loverboy, tell (well, text) him that he has no idea what love is if he thinks it happens via text and facebook. That's not love, sweetie. You should set the bar much higher than that.
