He shouldn't be saying anything 'filthy' at all and nor should you tolerate the 'filth' he swings at you. Being in love is fine but respect comes first..if he doesn't respect you, he doesn't really love you.
People gain weight, get acne, grow bald with age in addition to all other changes.. will he continue to abuse you then? Would he expect you to go thru lipsuction/laser/hair-transplant too?
