Trying to understand??

[peacetoday]

Have not seen nor heard from XH for many years
he left 7 years ago
and has no contact with his kids(school age) for like 4 years
but
I received 2 very large hospital bills with his name sent to our office

I called my XSIL to try to make sense of it and see if XH was ok
She said he was at her home a few months ago
He looked good she said and appeared to be "normal" and drug free
The family was going to help him get a job ..
but He was not allowed to bring W
He seemed like maybe he was leaving W

hard to understand the story because it seemed so weird
anyway when the family figured out W was hiding in his room
they kicked them both out
xh never asked about the kids
nor did he mention or talk about his mothers death 2 years prior
they said the W is psychotic and hears voices (sil words)
and sIL said xh said he loves w and can't leave her
they are together 7plus years
so xh left with W

I always still want closure and to make sense of it all
