Need help for song lyrics

Hi, i'm writting a song and i'm not sure of a few things since english is not my primary language.

I have this sentence in the song : "I'm not up to you" .
Does it even work, i'm not sure. What i'm trying to express here is that i'm not at the same level than a woman who rejected me. She is way more experienced than me in relationships and that's why she doesn't want me. If this doesn't work, can you please suggest a few sentence ?

Also, the sentence "I won't be seen through" to express that i don't want her to see through me anymore. Does that work ?

Thank you.
