Am I crazy to look back at our text messages to get a better understanding of what went wrong?

I've been looking back at our text messages and realize the major issues:

-He was extremely tired a lot of the times from working a lot and it was hard to respond at times. I should have respected that but I didn't and I'm so sorry.

-Not being confident in myself. Assuring me all the time had to become exhausting.

-I broke my promise to check in with how he was feeling more often. I said I would do that and I dropped the ball on that one especially towards the end.

-I pushed a lot of things like him being more romantic and I'm sorry for that too.
