Okay well first impression is that it leaves me wanting more, i want to know what happens with this old friend. I guess I will have to wait for the next chapter to get my answer. Until then we can focus on this one. 

I like how it is written like a journal entry especially with the scratched out "us" in the second paragraph. That makes the writing seem more personal, like you could read his thought process. Hopefully that was intentional. 

You do have what looks like a crazy run on sentence in:

We moved close to the kids – who like the normal teenagers they are, perform a cycle of loathing, ecstasy, self-loathing, and begging which is exhausting – and she is sure that they hate us, but I try to reassure us her that they are just young and thoughtless and self-preoccupied and doing much better because they know we are near and care for them.

normally a sentence like this would bug the crap out of me, and it did a little at first. But then i remembered that this is what looks like a journal entry, and i know that if im writing in my journal, the first thing i chuck out the window is my sentence structure. and once i recalled that i enjoyed it, a lot.

there is one spot in it where the word structure sounds awkward 

I have loved this summer; our first together whole summer in our own properly bank-owned house. 

i feel like the words "whole summer" and "together" need to be switched to read:

I have loved this summer; our first whole summer together in our own properly bank-owned house. 

besides that though, again, i really like it.

Hello ... for me this didn't quite deliver what it promised. It's not somethong "cops fear most" because nothing happens. It's just that it seems his wife hates him. Cops don't get involed in hate, only the consequences of it.

At the very beginning you tagged it "flash fiction". That it certainly isn't. That was careless, since I discover it's a chapter in an ongoing story. And in this case I suppose I forgive the author that there is no 'end', because there's more to come which is fair enough.

I have loved this summer; our first together whole summer in our own properly bank-owned house. We moved close to the kids – who like the normal teenagers they are, perform a cycle of loathing, ecstasy, self-loathing, and begging which is exhausting – and she is sure that they hate us, but I try to reassure us her that they are just young and thoughtless and self-preoccupied and doing much better because they know we are near and care for them. We are helping and they are better for it, I tell her. I hope it is not another lie.

Apart from the awkward long sentence which needs shaping, I would have wanted to have it quite clear that the kids in question are from a first marriage or relationship - or someone else's altogether. I would have thought that in this case she is sure they hate HER. After all, she would be the newcomer here.

The sentence:

our first together whole summer in our own properly bank-owned house.

needs to read, 'our first whole summer together'. I love the 'our own properly bank-owned house'.

And I suffered for it. Anguish, depression, anxiety, self-loathing, self-loving, self-indulging, self-fooling, perhaps

I'd re-write this sentence a bit because the guy who's telling us the story sounds like the kids a paragraph earlier.  With a dad like this ...

Still, I'd like to read more, and I'd like to read the beginning. This is GOOD! After all, no book is every finished before it hasn't been edited ... and again ... and again. That doesn't mean the story sucks!

A lot of it reads rather well.

I saw this 'tagged' as flash fiction?, but upon arrival I felt I was a victim of bait and switch. Scammed, yet again.

Now I see it is a chapter -I was not positive if that was part of the title, so I clicked and I faintly heard someone out there in cyberland excitedly exclaim: "Ah, gotcha! Heh-heh, another sucker."

(ha-ha)
