tl;dr : after argument my husband who works in another country didn't contact me last 3 days , I dont know if this is normal and how I suppose to act

​

My husband currently is working in Germany and he is there from 1 up to 3 weeks a time. After this time he go back to Sweden where we live.

Being in this kind of relationship is very hard for me but I agreed to this kind of job becouse he is making really good money and we are currently saving for our ideal home.

We have been in this situation from November last year and sadly a lot of my insecurities are coming to the light.

On Wednesday we had a fight where I get very emotional and he went kinda silence for day ( it ok for me ) then on Friday I proposed him a videocall date, I really wanted to grab some wine and have some nice converestions. Firstly he agreed but then changed his mind and said that I should focus on my project I am currently working on. When I asked him if there is a particular reason why he dont want to talk to me he asnwered that I focus to much on him.

Then I said that I guess no means no, and i dont have an influence on that, and also thanked him in very properly manner for caring for me and also silence myself for this night. Later I saw that he wrote to me in the evening that he loves me, and then wrote " good morning honey with a heart" on saturday morning I wrote him back " good morning babe" and from this day he went silence till today, monday.

On the app where we write he was last seen on saturday at 4 pm. ( edit : I have checked now, he was online yesterday at 00:21 and still no message)

I thought he need some space but its really making me crazy. I am affraid that something happend but also I wait for his move to write me first. I dont want to come as very controlling.

How i suppose to act now ? how to play this situations the best ?
