Advice please? Boyfriend problem!?

No one can tell you who to choose, you just need to make the right decision. If you love your boyfriend alot and your happy with him then why would you think about another guy? It just matters if your happy, and if your not..then go out with Jeff. You shouldn't feel guilty. Your only 19, and you have your whole life ahead of you and who knows.. you might meet someone else in the future.. i wouldn't take anything to serious because you might end up not liking who you chose in the future and you wont be happy. Just make sure your happy and everything will work out.. (: hope i helped. Good luck.
