i cannot believe her

Our neighbors are getting divorced. Actually, it was finalized last month.
She left him last summer. She cheated on him (for over six months)(whenever he was out of town on business trips)(in her own house with her three kids right there)(and lots of us neighbors knew about it)(i'm actually the one who discovered it)(but it was obvious after awhile... i mean, hello, we all live right here!) and then decided to leave her husband because obviuosly she was unhappy in the marriage. She moved out into an apartment.
They have three boys... two of them have health and behavior issues.
It's been a decent (although extremely hard and painful for him) split, very amicable and mature.
Except for the fact that I think she's so immature. Mostly selfish I guess.

But it's been a bad situation. Just sad really.
He was willing to do anything and everything to make it work and she just walked away suddenly (to him anyway) without a second glance back.
And turned all their worlds upside down in the meantime.

She has always been a spender.
She's also always been a stay at home mom, until the past year when she started working part time because all the boys were finally in school.
So they've got quite a bit of debt. And owe big time on their house.
Which he cannot afford on his own, and which she's obviously not helping with. Heck, he's probably paying her alimony and child support.
So he has to move the boys out of the only neighborhood they've ever known with their best friends and their great schools and sell the house.
He's had the house on the market for almost six months. Priced too high because they're already in the red on it. Now it's gone to short sale, but he's still stuck there.

And she still comes over to do laundry.
I cannot stand that she not only screwed over her (ex)husband, is screwing all of them over by making them leave the house, is screwing all of us over by forcing this house into short sale or foreclosure, but she has the gall to still come and go and do her freaking laundry for free in his house.
And he's nice enough to let her.

Here's the kicker though:
He couldn't afford to pay his HOA dues this year. That's not an option- you have to pay it. If nothing else, he'll have to pay it all anyway when he finally does get out of the house; he can't sign off on the house until that debt is paid as well.
In the meantime, since he's owing that, the family's neighborhood privileges are provoked. Meaning that they can't use the pool.
They can technically still be invited to the pool as guests with other friends, but they can't go on their own with their own facilities card.
The boys have been up there most of this first summer weekend with Family Friends from down the block. The dads are best friends, kids are best friends, moms are best friends; have been their whole lives, and have done a good job keeping it up (separately) despite the infidelity and divorce.
So Mom of Friend Family takes the boys to the pool (with her own four kids) for the day.
Guess who else shows up halfway thru the day?
And doesn't even hunt down and say hi to her kids in the water, just hunts down a lounger and plops down in the sun next to Mom of Friend Family. And proceeds to giggle away the afternoon sipping a beer and dipping in the pool.

Oh. My. Word.
I was astounded.
I have said all along that I cannot believe her, but really now, I CANNOT BELIEVE HER!
How dare she?

He is too embarrassed to accept an invitation to the pool with neighbors because he can't afford to pay for what we all have to pay for... but yet she'll flounce right in without a care in the world. And she doesn't even live here.
Or apparently care anymore what anyone thinks of her...
