I never invited her to visit, after two years of never taking us up on it I gave up asking.
She never got the see her GC, (please read my first post) us visiting every 2 weeks for a day wasn't enough and my family got to see DC more (they live abroad and would see them every 6 months).
Im a gold digger even though DH was at uni when we met, I supported him financially and PIL were normally working class so not rich.
That I risked my DC because FIl is a "paedophile". FIL wanted to go traveling and on his list was Thailand! This was a few weeks after DC1 was born, she was jealous that FIL was visiting every day for a few hours, we were very close even before DC we were close and in some twisted way she didn't want him involved.
She had no involvement in our wedding because she would go on and on that DH shouldn't get married to me
.
I stop DH from talking and seeing her after she was shouting at me walking down the asil (sic) that I was gold digger and a witch, the day after our wedding telling him and his children are dead to him
.
I don't let DH contact her when BIL tell us she has some life threatening illness after life threatening illness 
DH wouldn't help her out financially after her DH (DH father) passed, they had split for a year because she was having affairs and FIL said in his will the money (5K) was for us and our DC.
I wouldn't give her the funeral invoices so she couldn't claim back the money for the funeral. We paid and I refused to hand over the information so she could claim the money we spent back from the government and profit from his death
the only time I interfered he was like a father to me, visited constantly and would have done anything for the DC
