personally, i can never tell if a guy likes me. i guess because i never really expect it, and since i don't know how to flirt, if a guy has liked me in the past, he probably didn't pursue since he had no clue of my feelings (since i'm also very private about my feelings).
even if friends say, "yeah he likes you," my response to it is, "well, he hasn't said he likes me... so... idk." so do i want him to tell me he likes me? depends if it's mutual. but how will he know if i don't have dem skillzzzz? lol in my 1st relationship, he just straight out said he liked me. it just so happened i liked him, too. he just had to go for it and hope for the best. lol
