How Do You Stop The One You Love From Marrying Someone Else Besides You?

That's a tough one. I guess you can talk to them and see if they have any doubt about who they are marring and if they have feelings for you.

Yes you can talk to them but in the end you cant change some ones mind. You might want to let it go and find some one for your self

You have to show her your love without making her more positive of her decision.I think you need to show her that he doesn't love her ,like.....getting pictures of him with other girls .What i would do is pretend your a girl on myspace then pretend you love him  see if he says he loves you then send the pictures to her of what he said to you if he acted turned on.then she would see how wrong he is for her and she will trust you a lot more!!!
