She has decided to stay every Thursday night, that's the day we used to have sex. She has stayed over 3 times this week she slept on the sofa though, I said she can stay in the bed. She laughed today at a joke I made to my son after he said something.
All she says to me is concentrate on the kids.
Sounds quite good. I had been a little irritated, because she had left the two older kids with you, and apparently without saying too much about what is going to happen. I hope that you have not too much trouble accepting that the relationship with your wife is changing, and is more distant now than it used to be. As you said: this relationship to your wife seems to have been too exclusive, and so this gives space for other relationships. It is much better to have several quite important relationships (to your kids, to your ex partner, to your friend) than just one, plus several not so important, but more ore less meaningful relationships to more people.
