Well, I´m not sure what´s the intention of the thread. A warn? It could be, but no one knows the hearts, but God.
Married or single could do their play and make-believe roles. If you are "singled", with children, I can tell people here that I have seen those tricks to be lured away or accepted in a combo with their children "because they were left and abandoned". I have seen men (and woman) who stablesh relationship for flat conveniences (money) and not genuine love.
Of course, you are sharing what you have learned. It is painful and you´ve done right giving the world such a warn (it is) but very few poeple learn from another´s experiences (pitifully, but you tried to spare them some suffering you know the hard way).
I´m convinced IT IS NOT THE GENDER, but the sin spoiling people´s life. no matter it be from Christians or mundane, it hurts, same way.
