Looks to me like a song about a woman who marries a rich man to stay with her rich lifestyle "married your daddy with a different last name". But she regrets it and becomes bored sexually "every time you look at him you could just fall asleep", then she finds more pleasure in pain "you say your pain is better than any kind of love". This last line also suggests the fact that the 'pain' is an instant gratification (in her case) while love is something that can be very confusing and hard to come by, since she has never experienced true love, she takes her pleasure in pain.
