Every time I get a text or an email from H I put BIG effort into not reading it right away and managing my expectations. I sit and prepare myself for reading stuff I really don't want to read. In doing so I realize that I'm putting much more weight on the email or text than I should BUT, like you, it's hard not to see each communication as important. Once I actually do read the communication it's usually just some "business missive" but occasionally has been hurtful so I'm grateful I took the time before reading it to prepare myself. It takes very conscious effort.
Expect the best, prepare yourself for the worst. Managing our expectations through all this is very hard. It's easy to say have none but we're human and we have hopes which leads to expectations.
