Was tht a phone or am i developing any emotions for him or was tht was mere a curiousity?

hello. i m 18 yrs old girl.i leave at nagpur and my guy friend lives at mumbai.we have been clmates in my junior college .I once secretly came to know from one of my friends that he loves me very much (Which he hasnt confessed yet!!).Now after our junior college got over he moved to study at mumbai.Till recently we were at contact through orkut .,but then he asked me my mobile no. and i readily gave him my number.From then we used to talk at phone casually but recently he claimed me that i m not matured enough .Then when i questioned him this he said i m not matured enough in the sense to talk y and dirty things on phone.and top of this i dont understand NON-VEG things!!!it happend all of a sudden and I was shocked!! Then just for fun i asked him to teach me what maturity was! He began to talk dirty by sayying Non-Veg jokes and gradually we started talking like we are having PHONE !!! I was having fun too!beacuse knowing the guy who is in seretly love with you and talking was sounding good to me!!!we talked for about 2-3 hours late at night.he asked me wht lingerie brand i use or wht is my B***bS size! It was FUN! i want to know tht was tht a mere curiousity we did on phone or am i too developing soft corner for him ing to the fact tht i did not find the talks uncomfortable or bad!plz suggest!!!
