ris hooray! It sounds like you're doing wonderfully...so sorry I'd missed the last few of your posts but I've read through all of them now and am so happy for the progress you're making!
Regarding your concerns about him being dismissive when he replied 'Yeah', and the time he just got up and went to bed (I think it was that?)? Take care not to mindread (I think you already caught that though)... I can't tell you how many times I got those kinds of responses from my H, and I interpreted them exactly the same as you did! I assumed he was being dismissive, figured I'd said or done something wrong. However, as the months have progressed I've learned that it was quite the opposite. Most often when he'd present that response he was just simply processing the conversation and the situation we'd have been discussing. I came to realize this, when if the same topic would come up, he would react in a more positive, connecting way. The first couple times it happened I didn't believe it. But I kept track in my journal and sure enough, it was becoming a pattern. So, hang in there you're doing just great.
As far as the sexuality stuff goes, try not to worry about that 'something missing'. Our sex life went through the ringer. I'm talking years of only ML once or twice a year (blah). But the way my IC described it made total sense. Sex is the ultimate form of intimate communication and connectedness. If you're not communicating well or connecting emotionally in other areas of your life, don't think for a minute your sex life won't have those odd 'something missings'. It will happen, just give it time. So happy to see you're doing well! Keep up the good work. Yay!
I cannot complain for not receiving from others, that which I've never asked them for.
