TBH, YOU may be part of the problem. At least in how you are viewing someone else's marriage/family from the outside.
Here's why: Your entire post makes it seem like you are heaping it all on your sister and making your BIL and the kids seem like they are all "perfect."
I feel sorry for your sister. She is calling you up when she's down and you are looking for ways to further step on her.
You seem like you may be getting between her and her husband in a passive aggressive way.
Do you have designs on your BIL? Are you jealous of your sister?
This post went from helpful, to strange, to truly deranged.
PP, you are projecting, a lot. Holy smokes. You may want to think about why.
