Your kids could have a dad who isn't interested in skyping with them, like my H.
Sometimes what is best for your kids is not the least painful option for you. If you can learn to handle it, try to let them have as much of their dad as they can. Some OW eventually may be in their lives longterm, maybe this one, and blocking her out isn't going to be helpful for the kids.
I would have a hard time following my advice, but from a distance it seems like the best thing for the kids.
