That said, don't end a friendship just because you cannot control your feelings. Explain to her your difficulties, spend some time apart, but still communicate. Fantasizing about getting back together hurts, but these dreams can have a real part in the healing process, as long as you are aware they are fantasies.

I think you have to determine whether it is lust or love you have going here. If lust, it can be dealt with (regular walks, cold baths, beating it with a stick), if love, then determine what type. If it is the all abiding passion that one should have for a partner, then you're in trouble. If it's the other, the caring, concerned love for someone you want to make happy, then nurture it, turn it around and give it away. Above all, communicate your feelings. You will end up hurting someone sometime, but a little hurt in the beginning is far better to having your guts ripped out after years of half promises and fantasies.

Been there, done that.
