Thinker, I've been watching your thread for a while. We have one thing in common, we're both INTJ's and we're not the easiest people to read. With that I'd like to share something with you that may help.
Last week my W and I went for our routine annual eye check up. We see the same ophthalmologist and 'share' the appointment time. Earlier on in her life Mrs Gno (pun intended) had corrective surgery done on her eyes. Her vision has been causing her discomfort for a while and the results were not really good.
On the drive home I could see she was upset. I, being a dumb-hard-ass-man, wasn't sure how to communicate support through the freeze shield. Finally I plucked up the courage when we stopped at a traffic light. I put my hand on hers, gave it a squeeze and said, "Don't worry, I'm sure everything's going to be OK." Then I removed my hand and retreated to my 'corner.'
A couple of hours later she came into my office and said to me, "Thanks. Today I saw a glimpse of the man I fell in love with." And I got me a hug... from the ice-queen!
Don't look for earth-shattering ways to display your affection. Sometimes its the small simple things that we do and say that communicate affection. I hope this gives you some ideas.
