Sorry but I dn’t agree with what namita said. I feel that she will not dare to marry you and that is why she is searching a girl for you.
If you have been just friends, for more than a year than definitely you both should restrict your relationship as friends and always meet in presence of others. Never meet in lonely place.
Just search a girl who is beautiful and get married. Maintain distance with this lady and meet only in presence of family. Don’t give yourself any chance to commit mistake again, which may ruin your life. Make a firm decision to distance yourself from her so that no one ever gets chance to doubt you.
