Do texts slow down after the first date?

As to my last question. I went on a first date. It seemed to go well. Anyway, he didn't text me the day after the date (but he did text me when he was home). So I presumed he ghosted me. I sent him the ghost emoji this morning and we have text alittle bit. But I'm not sure if I am over thinking or what. But I just feel like something is off. He has slowed the messages right down. I sent him a message saying I had a nice time and all his reply was 'yes, it was nice. Xxx' now I don't wanna look weird or needy but is it normal for him to slow down the messages? When we parted on the date. He said he wanted to see me again and had a kiss goodbye.
