Can a 15-year-old girl move in with her 19-year-old boyfriend?
Absolutely not. The child would be picked up by the police and returned home and boyfriend would likely be facing charges for taking her in--and some of those charges could be pretty serious.
Your ex boyfriend now is with some other girl will just accidentally bumping into him and apologizing help?
Unless this girl and her boyfriend have agreed to have an open relationship in which they are free to have other involvements than the one they have with each other, you are going to risk terrible jealousy and conflict if you try to move in on someone else's girlfriend. Why not find a girl who does not already have a boyfriend? I'm sure that there are lonely girls out there who are dying to meet…
You can't have a girl if she has a boyfriend.. If she likes you she wouldve gone out with you. But i assume if you really like her you could wait til' they break up then you can make your move to see if she likes you. But since she has a boyfriend, leave the situation alone. If You cant wait. Try to get over her. Theyre are many other fish in the sea! :)
