(Fatwa: 636/621=L)
In Islam, it is prohibited to have love affairs with a non-mahram girl. Yes, if the boy and girl love each other in their heart with the intention of marriage and do not commit any thing unlawful then there is no sin. However, if she is already married to anyone else then it is haram for you to marry her.
