Input: My BF is 13 (so am I) and his girlfriend is 15 nearly 16 and really rich. When he started being with her, she was still with her boyfriend. She says how she's 'too pretty for him' and she should leave him. She also lives in America (he lives in UK) and could easily cheat. What really gets me is that they've decided that they'll get married and have kids + she'll live in UK and he'll move in with her by the time he's 15-16. In addition to that they also sext on video chat ALOT, I don't think this is alright and I'm very cautious because I care about him alot. Maybe it's non of my business but I'm just trying to look out for him.
