This seems to be pretty common behavior in your W. To me, this shows she has low self-esteem---a trait of many MLC'ers. Continue offering specific, honest praise, and maybe she'll start loving herself more. Once she loves herself, she'll be able to extend her love to others, including you.
I do, and feel like I always have, yet it barely seems to help. But if someone else offers some praise... boy oh boy, that's just the greatest!
Not too long ago she was quite pleased when her dad offered her some praise. This I can understand though, because she's often told me she felt her parents never supported her enough while growing up. And because I met her at 16, I know for a fact this was the case.
M: A really long time. Crisis: 5 years. She's still worth it.
Life is never made unbearable by circumstances, but only by lack of meaning and purpose. -Viktor Frankl
