I will not date, or get involved with anyone who is closer to my parent's age or my children's age than to my own age. Expectations, values, and culture/socialization are just too different in my experience.
Will also not consider anyone with drinking problem. Life and love are tough enough without trying to be with someone who exits stage left with a bottle anytime things get difficult or stressful.
Next......
PS. Good forum thread. Can't wait to hear what others have to say.
