<human>: Give me the gist of the text in a nutshell

Original : 

And she just gave us the biggest evidence we needed if she were to take us to court.

Was on Fiance's facebook, she started talking and saying "Never on facebook?" I told her it was me, she basically blamed me for all of this, and wrote "Thanks to you i don't even get to see MY granddaughter."

Told her i haven't done shit to stop her from seeing our daughter, and she replied with this, which proves she's just too lazy to come over.

I don't want to go to ur mums house get ignored by (Fiance). I don't want to sit there & stare at or put her to sleep. I'm her Grandmother I should  be able to come pick her up & bond spend time ALONE with her there was no problem with leaving here with me or asking to watch her when u were here y is there problem now*

Proves that she just doesn't want to come over, and that we're not stopping her from seeing our daughter

Conversation ended when she wrote 

She was when 1 to 6 weeks old it was fine for me to look after her at times (Because she wouldn't allow us to leave the house with our daughter) & u both know I can calm her down(You haven't properly seen her in over 3 months, she and what calms her down has changed) & I am quite capable in looking after My own Granddaughter. I know more than both of u put together on how to care & look after her. I'm sure a few hours at first would be fine for me to bring her here

and i replied "No, she's not going over there."

My god.
<bot>: Mother in law admitted why she doesn't want to come over, gave us a big piece of evidence if she were to take us to court.
