ladies, what y'all think it could be?

so this guy i've been talking to long distance (we've met and had sex and everything), just texted me saying he has to tell me something then when he called he got shy and said never mind and when i pressed he said he rather in person, he said he's afraid its not mutual, then i was like "r u gonna ask me to be friends with benefits or something?" and he said no that's far from it. what do u think it could be? he knows i like him. idk what it could be.
