The person on Twitter is named Yacine Ider, not Idder.
The name Idder has various variations (Ider, Iddir, Idheir) Yacine also, it is also written as Yassine, Yassin, and on it goes.
Djamel Idder, husband of Ansje, was a diplomat from Algeria.
If that was indeed so, surely it must be possible to trace the man?
The Algerian government must have data on him? Where he worked, where he lives, if and when he left the service and so on.
Djamel is also written Jamel, and the list of names on for instance Facebook is long. Info about him may be on the internet in Arabic writing. According to Google that would be دجيمل إيدير
Happy searching if you are familiar with the language! Google came up with lots of pictures of soccer players.
One of those things that I find so strange about this case is that Ansje apparently went missing with her son, gave birth to another son,
Skandar Rick Idder and then disappears for good with her children. What happened to the husband is totally unclear.
But somehow these children are not missing, the only person missing is Ansje. Perhaps that was the way of thinking in 1980, but surely we are not so dismissive about children now?
The Dutch broadcast "Tros Vermist" paid attention to the disappearance of Ansje various times. Their website was a great source of information, but for reasons beyond comprehension, that archive with the data of thousands of Dutch missing persons, no longer exists.
Fortunately, Tros Vermist also used ads in newspapers and info about Ansje can be found there:

MISSING
Ansje Neeft (woman)
Age then: 28 years old
Missing since: 22 July 1982
Place of residence: Brussels
Country: Belgium
Last seen: August 11, 1982, Harlow, Great Britain.
Appearance: blond long straight hair (cut short before departure), large blue eyes, oval face, pale skin colour and freckles, medium build.
Extra information: a few weeks before the birth, the very pregnant Ansje leaves with her three-year-old son Yacine the marital home in Brussels. She was about to emigrate to Canada with her Algerian husband, diplomat Djamel Idder. Ansje takes a sum of money with her and gives birth to a second son, Skandar Rick Idder, on 11 August 1982 at the Woman Refuge Home in Harlow, England. At Christmas 1994 there is one last sign of life when she calls former colleague Marleen of ITT Brussels. Ansje may have built a new life elsewhere under the name Anna Neave.
The text specifically mentions
emigration. This is confusing, because diplomats and their families usually go from one post to another and as far as I am aware this isn't called emigration.
I'd be very interested in Djamel Idder's career. I don't think the children went to live with their father, if Ansje had wanted to leave them behind, she would have waited until after the birth. Instead she went to the Woman Refuge Home.
I also wonder if they got divorced and how? A marriage does not end if one partner disappears nor if they change their name. The documents about a possible divorce may also mention what happened to the children, or should have happened, depending on whether they were located.
