What does this mean?- the WH's regrets?

[gatsby11]

About the time thing: he didn't realize that I needed him to come over so I could do stuff. He thought we were going to hang out. (Poor WH doesn't think too much about reality!) So he realized that he didn't prioritize the time and was apologetic. I laid out at the pool, went to Whole Foods, and then did an intense walking-hills exercise! It was very nice to get out. I also made us a pizza so we sort of did the dinner thing.

But, P, since I was mad at him for changing the time, I wasn't very welcoming when he came in!

I tried to amend for that, though, after I realized he was sorry and he didn't understand fully. It's so weird that communication has to be worked on even when you're not actively in an R.

He'll be back again tomorrow...
