i think he answered it indirectly. "i have no desire for confrontation" = no, he probably hasn't talked to her.
also, i hope his response makes it clear he doesn't want to go into much detail regarding the situation. no matter what his reasons are, i think we should respect that and let him continue to develop as he sees fit.
i understand why you want to get them to resolve things peacefully and potentially have lip and her content back here, but they're both adults. if they want to reconcile, they can do it.
it's sad to see how lip lashed out, but i genuinely believe she had an unhealthy attachment to the game. this is probably for the best, drastic as it may seem.
