Should I confront him about this or should I let it go if we talk normally again?

So I have been a little upset this week, because my boyfriend of 7 months, which is older than me (he is 46) I am 30, has not text me this whole week, on Tuesday he just send me a video through Whatsapp, I rather a ’‘Hi my love’’, not a video.

He likes to send me videos that his friends send him, sometimes funny, society, science etc, the one he sent me was more about people interactions in Asia or something like that, I was annoyed cause I was expecting a message, so obviously since it was a video I did not reply, I just felt like meh, whatever.

I want to mention that this man has been very good to me, he has been very giving, loving, attentive, have details, etc. His family came like 2 weeks ago and I met his mother, aunt and stepdad, his mother liked me a lot.

This past weekend I stayed over his new bought house(which needs a lot of fixing and has him somewhat stressed) and everything was fine, we went out, had fun, I cooked for him.
He is worried about the amount of money he has to put in this house to fix it, but he already found someone who is going to help him with some things for way cheaper. He also needs to find a person to rent an efficiency that the home has (they build the garage as an efficiency) to help him with the monthly mortgage, so he wouldn’t be that tight.My boyfriend has a good job, that pays him well, but it’s way too much money he has to invest in the home, so it’s not enough.He has his hands kind of full now with his new house.

I don’t know if something is wrong, and he got mad that I did not reply to the video, which is silly cause you don’t reply to a video, I do admit that I like him to always initiate contact, I have this issue from a long time, that I feel better when the man initiates contact, maybe he is mad that I never text him first?

Or he does not feel the same way. I know he has been getting online on his Whatsapp, maybe not a lot, but he has been on it. I don’t know what to think.what do you guys think?
