I like a girl but she has a boyfriend

I met her 2 months ago, through a friend in common. She visit my city for work.. and I was the only person she know.. we hung out all most every day.. start have a great filing for her so and she.. we sleep in the same bed without have sex ( for many time ) , even if try with nice way..with out puss her.
the problem is I start be in love with her.. I tell her that I like her,,and fill great with her.. and never before have a girl ( friend ) to be so close . she doesn't reject me.. but she tell me that she like spend time with me. Or she is not in love with me..and in the best she was with other person and after 5 month she love him.. but she have a boyfriend that she love him .. and maybe later she change idea.. what I can do.. is hard to me to hung out with her as friend..to be next to me and I can not touch her .. all so hate to be the 3rd person..

It sucks being or feeling like the third wheel. However, it seems that you are also very close with this person. You should ask yourself if this girl is someone that is special enough that you would go out of your way to win her over. If she is, then I say that you should go for it. Love is a complicated thing and you cannot help falling in love.

If all else fails, love, lose, and fall in love again, but don't ever just let love pass you by because you'll regret doing absolutely nothing.
