Mean in the "went no contact (and mean when we do have to have contact for one reason or another) overnight, for seamingly no reason and don't want to tell me or anyone else what's wrong" way. Actually they promised me that they were going to tell me what their issue was, but they never did. It is the second time something (exactly) like this happened with this person and the first time they made the same promise, and did only tell me after an important event that can not be reproduced this time.
Won't work sadly. It already happened before, got solved by a true miracle (I don't want to share here what happened, but it was the most impressive "right time, right place and right people" thing I've ever heard of). And I wanted to talk (still want to talk btw) but they don't.
Last time I saw their "normal" self they really appreciated me but that seemed to have changed overnight (literally).
That's very sad. Maybe it would be better for the children if you divorced and they had two seperated happy parents instead of you two being unhappy together. It's your life, I'm just some stranger on the internet. Hope that you get better.
Very nice artstyle
