so i've been kinda dating this guy the past month or so. we havent had "the talk" but we've been basically acting like a couple. he calls/texts me everyday and we usually hang out everyday, we cuddle and have sex and have slept over at each others places quite a bit. anyway last night i went out with some friends and ended up hard core making out with a few randos. i mean... the guy hasnt asked me officially to be his girlfriend so its not really cheating but i duno if i should tell him or not?
