Well my two cents would be to take care of yourself !
If this is what YOU need then go for it.
Just keep in touch with the kids daily and if H wants to talk then he will.
I would just explain to him before you take off that this is what you are thinking and atleast allow him some input. If he shows you that he does not care then do it !
best of luck !
