A very close guy friend stopped talking to me after..?

[Lamita]

well ive known him for five years and we are very close . anyways a year ago he's been chatting with me alot and since he is an old friend i really trust him , but chatting ended up to b more like sexting and had a few times sexual touching. but i never sent him any pictures of me. the thing is, i felt he is using me. he is having a one year gf. ive known him and his sister since long time ago and guess that explains things. so i had to stand up for myself everytimes he tries talking dirty and he apologizes afterwards. yesterday he slipped the dirty talk again so i told him that " i know i have let u before but everytime i think about what i did I start crying" so he was like " sorry sorry sorry, im really ashamed" beh... so we kept talking afterwards other random stuff so i asked him this question" y dont u love me more than a friend?, am just curious" he answered " its not like that.. i dunno wht i feel , its weird and dunno wht to say..ur a great person, and a very special one u knw that..u knw me I'm always honest with u" so he stopped talking so we changed the subject and I said bye couple minutes later.. today he didnt speak to me, no hi , nuthing ,,he did talk everynight,, does that mean that he only spoke to me so he might get some sexting.. or is t bcoz of the" y u dont love me" question?
