What does his looks have to do with his personality? Is he a trustworthy person? does he give you reason NOT to trust him? Does he lie? Has he cheated before? Does he keep or hide things from you? Is he honest and open with you? I think those things are a way better and good indicator as to whether you should trust him and not the fact that he is "confident and good looking" Look at HIS PERSONALITY, his BEHAVIOUR, his MORALS and VALUES, not his looks. That won't make him stay when the times get rough! Hope that answers your question!
