It is there way of being the man, showing you that they are in charge or superior to you, that they are well basically just disrespect you and have no respect for women in general, and when you take into account that he is cheating on his wife with you (case in point) he has no respect for women and or their feelings. This is why he says things like that. Find an unattached man, with respect and manners, someone that will hopefully love you and respect you and treat you as a person should be treated and if you are lucky. He will not meet some one to walk his dog with and break your heart.
