suggestions ?

I've been talking to this guy for about two months now but I'm starting to think I'm his side girl ....😳 we talk everyday but sometimes when I text him he reads my message but don't reply ... even though he has his phone in his hand .he always sayin im annoying him but wants to talk to me! sometimes he's supposed to come over my house to chill but something always magically come up. then today he told me he don't really fwm but he scared to stop talking to me because he thinks I'm going to kill him 😂 lmaoooo! he says he was just joking but idk ...I think him and his ex are back together but he says there not. he's never lied before but idk what to think  😕
