Ok here is what I think.

I think boy should stop being in love with girl for a few minutes or so and be her best friend. I'm really bothered by the fact that boyfriend is not spending much time with girl. If they do get married the time spent together will only get worse. I kinda want to know why boyfriend is neglecting girl so much and I want to know what he is doing with his time. Girl needs to think about whether boyfriend is the right guy for her. Some soul searching is definately in order for her.

Now if girl does decide that boyfriend is the man for her then boy should still stay friends with her even if she spends less time with boy.

I hope all this is happening in real life and none of this is only online. If boy lives far from girl, but boyfriend is there in the same locale as the girl then boy probably won't get the girl.

In any case, I wish boy and girl lots of luck.
