Taking a week off texting /talking

my husband (48M) and I (48F) have been together for 20 years and for work he moved to Asia last year. he is so happy there. I was with him for 9 months, but had to move back so our daughter can graduate from her high school. he told me when I got back that he was extending from 4 months to 10 months. we are caught in a horrible dynamic. I miss him, cry, obsessively check my messages. I even requested he text me every morning and every night at the very least. which he does because I asked him to, not because he would otherwise. I only get spontaneous video chats that are kind of vapid and two word responses to maybe half of my texts. you can imagine how horrible this is for both of us. I'm yearning to feel connection and he is feeling mostly like i am a chore to be managed. for both of us, we have gone from soul feeding to soul sucking. and we have 9 more months to go.

very important note: we have an amazing marriage and I know he is totally in love with me and devoted to me. we will be together forever. but the big realization I've had is that at this moment in time - after raising 4 now adult kids and all of the baggage from running a household - he doesn't miss me. he feels liberated. not from me but from domesticity. amazing. awesome for him.

he doesn't really "miss" anyone - he is a very present writer and author and artist and loves long periods of writing time. there is nothing for me to resent about that because it's always been true and part of what I love about him. his sustained focus and commitment to his work.

he comes home in one week after 3 very long months apart, and I'm afraid im just going to unload on him. he's feeling like even when he gets 5-6 hours of focus time it's not enough to reach out to me. he has close friends and a roommate abroad which I know are way more invigorating than responding to one of my "why are you not sharing anything with me" text messages.

so I did something I think I needed and have been wanting to do last night: I told him I'm going no contact for 5 days (a few days before he leaves). at the very least this releases me from constant phone checking and expectations that land on him like neediness. I blocked him on everything except email so I don't have to see chats of mine unanswered and wake up to an empty phone. it's an experiment and I woke up this morning feeling free.

but I did it without a conversation about it. I told him I was doing it and then I immediately and happily blocked him across chat channels. I'm checking in here because there is a part of me that feels like this is a mean, abrupt and harmful thing to do to my husband. I just don't want to "talk" to him about it because he will probably deny that giving him all the freedom and space is what he is wants. even if it's what it is.

did I do something healthy? or am I being childish and over dramatic ? thank you for your feedback. regardless of what I did I feel incredible. I just also feel a little guilty. I'm a head case. it's hard missing someone who doesn't miss you back even when the love and devotion we have is very real. this whole situation sucks.
