My husband never, literally never, says anything nice about how I look. He never criticises my appearance either. He just doesn't care. At most, if I badger him I'll get "it's alright" but even then it is mostly "dunno" (aka don't care) and a shrug. I don't badger him btw. That response is worse than no response.
A few weeks ago I was a bridesmaid and felt very self conscious about my dress. I actually asked him for a compliment because I felt awful and he just smirked. Today I have had a big hair change that is so different to anything I've had before that there is no way he wouldn't have noticed. He hasn't even acknowledged it.
I challenged him once and got some glib "you always look nice" lazy rubbish. Blatantly not true.
On the one hand, sod him, I don't need his affirmation but on the other hand, it would be nice to hear him say I look pretty sometimes, especially when he knows I'm feeling bad.
