hi harry76, and

you love a very highly sensitive, and reactive person.
have you ever shared something with someone, and been underwhelmed by their response? we all have. and for most of us, its disappointing, or it can even be hurtful.
your wife experiences that on an even higher level, and she experiences it as a rejection of, not just her, but who she is.
now, its going to happen. you cant walk around reading your wifes mind, and feigning intense enthusiasm for everything. not only would it not be possible, but it wouldnt be authentic.
but understanding where shes coming from on this can go a very long way.
'Oh so now you want to see them? Are you mad at me because you don't like the way you look in the pictures? whats wrong with you? why can't you be happy about sharing this stuff?'
I respond saying 'you literally showed it to me while I'm fully doing something else, now I'm done and very happy to look at it again'
when she overreacts, taking it personally or being defensive (JADEing) will rarely ever help.
reading between the lines (shes hurt, feels rejected, and wants a little reassurance) is key strategically. how to give it is tricky.
