Guys, Post first date communication?

I went out on a date with a man on Friday and it went really well (it lasted about 6 hours) and we kissed at the end. He made a few references to subsequent dates. He’s a little bit older (early forties) and I noticed before his texting was pretty cut and dry but he would wish me a good morning and ask questions about me etc.

He asked me to let him know when I made it home and I did and told him I had a great time etc. he texted yesterday morning as usual and yesterday evening but both were shorter interactions which happens when he’s busy. He didn’t text this morning so I reached out and he responded but that was it.

Is this an indication that things are fizzling out? Or is it normal for communication to die down to some degree?
