her parents have normal relationship with eachother, but not as open or great as one could expect. when her father is at home, he is usually watching movies. he doesnt take them out neither plays with them. but i can not say they have unstable marriage or relationship. we ask them to go out with us as a group but they dont. so we take her with us. but she grew up in that environment.
we tried to talk to her parents to change themselves, spend time with their kids, take them out, and enjoy life with them. but they dont listen.
Even if the did have a horrible marital relationship, the kids aren't supposed to be a victim of it. Anonymously send a social worker at her house and it will fix her mischievous and obnoxious brain cells. Or make an anonymous call impersonating a social worker from the kids school, reach out to both of her parents and tell them that their kids are acting weirdly at school, and their teacher is afraid that there might be some kind of child abuse involved.
I can never imagine of reacting badly to my kids when i am having issues with my hubby. Kids are kids, and a parent's relationship with kids should be independent of what his/her relationship is with the spouse. It's that simple!
