What did she mean when she said she tries so hard with me but gets nowhere?

So some context knew a woman from work who we would meet up outside of work with two other colleagues she knew I liked her as I told her but all she said back was what do I like about her and how do I like her, she hand feed me a few times we would bicker over the dumbest things song songs to me and said one song reminds her of me,, I don't understand why she said she tries hard with me but gets nowhere? I'm 35 she is 30
