my daughter loves an angree man.

What is "angree" ? Anyway, you can't live her life for her. You can tell her your concerns but ultimately it's her decision to make. She needs your support not your criticism. Who knows it might work out it might not. The last thing she needs is you telling her "I told you so." If she is grown she has the right to make her own decisions. Nothing you do will stop her so stop talking bad about your soon to be son in law. If it's a mistake she has to make it on her own.

This ties right into your other discussion about love being blind. She loves this guy therefore she does not see him as an Angry Man like you do. All you really can do in this situation is be there for your daughter when it blows up since she is not willing to see this guy for what he is and the more you push the more she will pull. Just what ever you do do not alienate her since if he is this bad she will need you really soon. Remember the old addage "you can lead a horse to water but you cannot make them drink!" You have done all that you can really do by telling her what kind of guy he is, you lead her to water now only she can drink. I wish you and her the best of luck! HAVE A GREAT DAY!!!
