Takes ages to reply to my text regarding talking our relationship?

Hi

I was seeing this guy for a few months everything was quite nice but suddenly he pulled off because he felt I was distancing myself which wasn’t true.

its been now 2 weeks that everything is weird , he came home to see me hugged me promised we would see each other he said he thought I was trying to break up with him , we made up but then he won’t text , call etc whereas he used to text everyday all the time very consistently and being very loving to me IRL too.

so now it’s like it’s over. He just watch my stories everyday but won’t text , communicate with me.
i told him we need to speak and this is what he wrote to me

I have messaged him to say I would like us to talk about what is going on that perhaps he doesn’t need it but I do , he told me ‘Hello, yes, I am very well, and you? we'll talk tomorrow evening. no problem.
Tomorrow night I'll finish a little later around 2am and Sorry for Tonight I just wanted to go home. Have a good end of the evening. Kisses’
I said ‘ok great , good night kisses ‘ and he replied ‘ good night you too kisses ‘

Then the next day instead of meeting with me he went home , I texted him in the morning this
‘Hi, I hope all is well? I understand that sometimes things may not go as planned and it may be better for me to see you somewhere else than at your workplace in fact.( I live above his workplace) I'm available today Until 4 p. m., or tomorrow tell me and I'll meet you. Good morning, kisses’
He replied an entire 16 hours later past 2 am after work :

‘Hi, I admit it's complicated right now. I'm sorry to blowing you off like that. Don't worry, we'll have the discussion you want to have I promise Have a good evening. “

( no kisses this time when just yesterday he was sweet )

Now he just takes literal hours ( 16 hours + to reply to one text?)

What’s going on? Thank you for your help
