Again, not a veto as far as I can see. You both agreed with your wife to end the relationship. A veto would be if she DIDN'T agree and you called him up and said, "sorry buddy, yer out," while your wife cried "nooooo" in the back ground. This didn't happen by the account you are relaying; not a veto.
