Why my friend stop talking to me first?

[Lady]

So this past days,my friend guy been acting weird.He used to text me first,but not anymore.So,yesterday i texted him first.

This is the coversation with him.

Me:Hello? :s
Him:hey
Me:whats up?
46 mins later - Him:gonna watch my show, you?
Me: oh,nice i should watch it too
no reply (he always reply and start a new conversation but this past week he hasn't.
so, i texted him 1 hour later.
Me: When you gonna come over to my house?
Him: I don't knowwwww
Me: What???why????
25 minutes later - Him:yeah
Me: what you say yeah?
Him:idk... im not coming
Me:wtf??why not?
Him:i told you idk so just leave it like that
Me: omg []:
Him: lol
Me:...................



So the conversation ended like that (

Why he acting like that? He doesn't text me first anymore,and doesn't want to hang out at my house anymore. Should i stop texting him?I want him to be like he used to.
