Are we talking about MALES in general regardless of relationship status?
I made the mistake of trusting my father as a child not to hurt me and walk out on me and expected him to be a dad. Should never of done that, he was a lousy a$$ father, and worse husband walking the planet (IMHO).
I've learnt my lesson-never trust anyone regardless of your relationship to them. Men are culprits for me, sorry if that's sexist but life doesn't always hand you a far hand.
I do trust a few men though-my husband and father-in-law and youngest mamu.
