What him being a bitch and forgiving his cheating whore wife we since it is a kinetic novel we all know it's going to go the basic cuck route.
It is possible. So far, he didn't "accept her back", he said he would consider and it was mainly because he wanted to find a place for his ex-gf/daughter to stay due to an immediate issue.
As it stands, the story seems to be heading towards him being with his daughter, which implies there will likely be something with his other daughter, and possible ex.
If that focus continues, the wife "may" be kept around as a part of a harem concept, at least based on the current state of the update.
It is not uncommon to see a netorare start (or back story) that continues into something entirely different. I am unsure if this is the case with this one.
It could be as you say, another cuck trap and all things considered, I wouldn't be surprised due to the common approach to many of these types of games.
I would be leery either way.
