I STILL LIKE MY EX BUT DOES HE?

Ok so my ex said some really mean stuff before and he gave my reasons why he dislikes me but after that day he apologized saying sorry and that he wasn't in a very good mood. Then after a couple weeks he then texted me saying Hi and asking me what i was up to then i texted him back asking him what he was up to, but he left me on read. Now after like 4 weeks he texts me again saying "send nudes" but then says "sorry that wasn't me" i said " okay". but a couple hours later i asked him who it was and he left me on read again?!. Also there was also this time I was sitting next to my friend then my friend calls my ex (saying his name) and he looks at my first then my friend? Does any of this stuff mean anything? I want him back tbh. If this sounds like elementary to you idc lol i just like him and i need help whether or not this means anything to ya'll?
