Would a smitten guy lose interest if a girl rejected his kiss?

My best guy friend tried to kiss me and I didn’t reciprocate because I was shy. He seemed hurt but told me it was all cool and still kept contact and remained touchy and lovey dovey after that incident, hugged me all the time, kissed my forehead and called Mrs beautiful and cute every 5 minutes however he claimed that he lost romantic feelings for me. Was he ever smitten with me? He would still tell me he missed me after that incident
