I don't think there's any selfishness to disappointment? If you're disappointed, you're disappointed! It's a "disconnect" of sorts and that disappoints one.

I know I often have to work with myself because I'll talk about my thoughts/concerns first, especially in e-mails, and then either "forget" to comment at all on what the other person said or I'll remember and go back to the beginning of my response and add a sentence or two (at least) in reply. My T had to work with me for 6+ years, literally, in person, to teach me to "respond" to the other person when they are actually there, giving me "clues"! So I can see how easy, with text only, it would be not to get any clues and only talk about what one is focusing on at that time in one's real surroundings? Hard to have text on a phone compete with a big deal going on? Can't "grab" him like your warm voice :-) might have been able to.

I would wait until you have his attention and let him know you were disappointed and help him learn more about you, what pleases you, what disappoints you, etc. If you do it with your warm voice :-) he might "catch" himself next time because he does care whether you are happy, just doesn't know what makes you happy and is important to you?
