Ok I tried so FUCK HER!!

So I posted about my dads wife's threatening not to watch my kid's after offering because we were gonna go to a casino she liked, so i deleted her off facebook and had no contact.

fast foward 2 month's of no talking; we were suppose to go up to my dad's house my son's bd weekend(oct 20th)but everyone got sick so we made it for oct 29th. I didn't want to go for the simple fact that I didn't want to deal with her but I did it for my dad. Everyone kept telling me to let it go, have fun, carve Pumpkin's and open presents so we did. Once we got up there I can feel the instant hate flowing around the house; we were all very uncomfortable she talked to me and I talked back then I can tell her mood changed instantly. She was stomping around the house getting an attitude with everyone; she spent 99% of her time outside then she walks in and says "so are we gonna let them open presents or are they gonna stare at them all night?" My step brother's kid's were there too and tomorrow is his daughter's 2nd birthday. I wasn't sure if they wanted her to open hers yet so I just let my son open his, she didn't even watch she stayed in her bathroom the whole time. Well once we were done she walked out and seen that Willow(her granddaughter)didn't open up hers and she freaked out so she grabbed her other granddaughter from her son and sat down to watch her open up her gift's. A little while after She grabbed my daughter held her for 20 min then handed her back saying she is heavy (she is 12 pnds)then went over picked up her other granddaughter and held her for at least an hr(she is 20 pnds)then gave her back. After that I put a pair of pjs on my son that they bought and I told him to go show her; he run's over and goes "grandma grandma" she look's and him and yells "WHAT!" He opens his arms to show her and she's like "cool" and turned away. We were getting ready to leave and I went to reach for my daughter and my dad says to let her bye to her, well she was bending over to pick stuff up off the floor and goes "bye" and walks away. He tell's me she is mad at me for deleting her off facebook because now she can't see pictures of them. But the way I see it is if she cared that much about seeing them she wouldn't have threatened not to watch them over something stupid. She claim's to be their grandma but pulls shit like that; then gets mad when I strike back. So as far as I'm concerned she doesn't need to be part of their lives. After I left I messged my dad and told him how I felt... Did I go to far? I mean idc if I did you don't mess with other people's kid's and treat them like shit because you a problem with their mom.

Before you comment make sure to read. I wanna make this clear! I am not mad because she wasn't gonna watch my kid's; I could really have cared less. I am mad because she OFFERED to watch them and when she found out where we were going she used them against us by saying she wasn't gonna watch them if we went to the casino she liked because if she couldn't go no one was. She OFFERED!!! We didn't know she even liked that casino until she flipped out.
