She is an empathetic person.

 

By revealing private info and showing vulnerability, he takes down her guard because she always wants to help. By asking her to analyze his feelings, he provides her focus.

Depending on what motivates him, it can be good or bad.

Is she clear in her mind what defines her "self"?  When that boundary is being pushed or crossed, can she be congnizant of its happening? (Here, the "boundary" is not physical.)

Ask her to discern if he is a person with a kind heart. That is different from being nice.

 

"开始我女儿并不喜欢他", does she know why? presumably this was prior to knowing his background.
