Worst Thanksgiving Ever

This Thanksgiving was the absolute worst holiday I've ever had. I got to my family's house in the morning and heard screaming from inside before I even opened the door. My mom and my sister (who's 22) have been known to go at it every once in a while, but this was next level. Apparently, my mom deleted some Facebook messages from her phone and my sister apparently thought that was really suspicious. The screaming went on for 30 minutes before I couldn't take it anymore. My sixteen-year-old sister was in the kitchen while they were fighting and no one seemed to think that it was inappropriate to be doing that in front of her. I grabbed my sister and took her out for coffee after yelling at them to pull themselves together before we got home. We didn't even end up having a Thanksgiving dinner. I'm still so angry at them for being so selfish and immature that I haven't spoken to any of them since Thanksgiving. What should I do?

How can I get my mom to stop over sharing?

My mom and I have had a very close relationship since I was a kid. I know I can tell her anything, I mean anything, but I like to keep some things private. She, on the other hand, tells me every little detail about every part of her life. This was fine until she started going through what I'm pretty sure is a midlife crisis (I'm not trying to be mean. She's just having trouble with her marriage, dealing with my troublemaking sister, and generally just realizing that she's not living her life the way she wanted). Now she's having an affair and experiencing a sexual awakening of sorts. I'm happy for her, in a complicated way, but I don't need to hear the details of her newfound sex life. How do I nicely let her know that I'm uncomfortable with the topic?

Your Parents Or Your Kids

Call my crazy but when it comes to devoting my time and energy, I'd rather spend it on my own kids than on my parents. My husband, on the other hand, consistently chooses his parents over our two children. For example, he will choose to give his parents a ride to the airport over taking/pick up one - or both - our kids to/from a playdate. It's frustrating as hell. I love my parents and I am there for them when I can, but with life being so full and hectic, there are many times I will tell them I can't help them with whatever they need and instead focus on my children. Am I wrong? Adults should be able to solve their own problems. And it's the children who should be the priority, no? My husband disagrees with me.
