This is an excellent post. And true, TS/LS has a legal right to live in the home. It is one of the things that has caused me to wonder about some things.
I GUARANTEE my wife would NOT let my ex live/stay with me in our home, even for one night, even under this circumstances of this case. IN FACT, I MYSELF would not permit it, simply out of the love and respect I have for my wife.
So yeah, something smells fishy here with this arrangement.
Hate on her if you wish, her demeanor being what it is, her self centered behavior, the harshness, the coldness, all that being what it is, there's a little piece of me than senses there's more to the story here.
