Your ex husband— okay technically he’s still your husband but you’re split right now. He’s so irresponsible. I mean you have to teach the children right from wrong, meanwhile Satoru is fighting curses or feeding them all the candy/sweets Japan has to offer. Not to mention he forgot your anniversary and stood you up twice. You’ve caught him flirting with other women (regardless of whether he actually meant to). So you split. Now you’re both co-parenting until you can muster the courage to try again or divorce for good.
