Does he like me? what should i do?!?

i have a guy friend, who i've been friends/known for 3 years, who i recently became really close to and now i like him.. and i have for over a year. i finally told him, but by text in october (both of us are shy) first he said his feelings were the same, but then the next day he denied liking me (had a friend ask him by text)... we both have never been in a relationship either... but one of my friends and all of my family says he likes me(and me). my other friends say no because he said he didn't. he does things that show he likes me, like showing off, hanging out with me, calling me everyday, texting me, hanging out with me during passing periods (didnt do this before). stuff like that...i asked him to a dance (girls choice) and he said yes... we went, but he wouldn't slow dance...i was thinking about asking him out by asking to see his phone and changing the greeting to ';will you go out with me?'; but im shy and afraid he'll say no... and i couldn't figure out how to change his greeting...my friend said that everyday he hangs out with them after 1st period (same class) and ALWAYS asks where i am and once they say they don't know, he just walks off..my friend thinks that he denied liking me and didn't slow dance with me cuz he wants it just between us two, and not our friends...my mom doesn't think i should ask him out. she thinks he should cuz he's the guy... but if i wait, i don't think he'll ever ask me out cuz he's really shy and has never dated before... what should i do?!Does he like me? what should i do?!?
Nice flirty way of indirectly asking him out = something along the lines of ';You don't have to be shy. If you ask me out I'll say yes.'; XD I know it's over the top but everyone's afraid of making a move you know?
