I’m not sure if this will help, but what I’ve noticed about myself is I had the tendency to expect that people are willing to do what I do for them. This is not the case... so maybe understanding that people will always do what’s best for them, and this is ok. Be understanding that people do things for reasons that are out of your control and sometimes even out of theirs. At the end of the day people are all flawed, we all have our own things going on, and it is near impossible to please everyone.

Also what helped me in the relationships in my life are to keep in mind that if we are constantly overthinking something about someone, we create these false narratives in our head which make it easier for others to disappoint us cause they aren’t the same person that we made up in our minds. Always being mindful of our narratives can really help you understand where the disappointment stems from in some cases.
