The guy I like said that he is happy he is taller than me when I am in heels because it is good to know for future references if we go to formal events together... what is he thinking when he says that? He has never made a comment like that before, his behavior towards me has been changing a lot. He also asked if I had my seat belt on because he 'just wants me to be safe.' A lot of compliments and sexual hints have been thrown in the mix too... He has never done this before. How should I approach this?
