Is it normal to be physically& sexually atracted 2 a friend?

i have this friend, and after i was very upset about a terrible break up (got cheated on) then he kissed me.& it has progressed ever since.anytime we get the chance,we make out & he feels me up,& he even fingered me once. It feels wrong & not normal, but when i'm in the moment, i can't help but want it. is this normal?
