Why does your man always compliment other women?

If he compliments you often and also compliments other women then he's being a gentleman and you should be proud of that good characteristic in him. If he seldom compliments you and is always complimenting other women as you say then he's flirting and things he's 'hot in his socks' a type of arrogance. Nip this is bud and tell him to knock it off or hit the bricks.
