Husband moved out...

[peaceSJ]

Finally H moved out after he dropped the bomb nine month ago. H claims not being loved for so many years and now he wants divorce.

So far he came back home every night after picking up kids from school. While I was cooking dinner, he did his own stuffs on his computer or iphone. Then after the kids went to bed, H left. Every morning I dropped off the kids to school.
But I know finally H will not come home every day; he already suggested to take the kids to his apartment with him for three days a week and then he does not need to come back for another four days.

I asked H about the reason for moving out because the apartment rental will cost us a lot of money; He replied since you don't agree to divorce, I have to move out. No couple who want to divorce still stay together. Our house has an extra bedroom and he can stay there which can save us a lot of money, but he doesn't want to. Anybody here can help me understand what is in his mind?
