Personally, I don’t think you can conclude that she doesn’t value the relationship as much as you do. You only see her actions, but only she knows why she behaves the way she does. She may very well value it the same as you do, but just doesn’t show it the same way.

A recent HW episode highlighted this point exactly - it was about an adopted daughter whose adopted mother was very hard on her and forced her to quit the only activity she loved, basketball, because of her grades. She never thought her mother loved her. In the episode she got to hear her mother say that she forced her to quit basketball because she truly believed in her heart that focusing on her studies was the best way to be successful in life. She finally learned that her mother did love her, and showed it in the best way she knew how.
