AITA for keeping myself and my child away from my husband's family.
My husband family is very sweet, kind and we love being around each other. Just recently, I found out my sister in law is cheating on her current BF once again. My SIL is 30 years old and has cheated in every relationship she has been in. Even if she is happy in her relationship, she will entertain other guys and go as far as getting money from them. I don't agree with her behavior because I absolutely do not tolerate cheating. But that is her life and her choice, and I also try not to judge too much. In this case SIL has a 9 year old daughter that calls SIL's BF step dad and his kids her siblings.
This is where I feel like SIL has crossed the line. SIL's current BF is the laziest bum I've even met. He will not take care of his own children but plays step dad to SIL daughter. He doesnt like to work, but tells my SIL she can't lose her job, doesnt cook or clean as she works 12hr shifts. Why SIL hasn't left this bum?? She has big support mentality and physical from the family. She will complain about her BF non stop but cant leave him.
She started talking to another guy, this other guy knows she is in a relationship and she doesnt want to leave her BF. The other guy is okay with sneaking around with her. My SIL goes as far as to take her daughter around this other guy, while her current BF watches her daughter when she is at work.
The other guy picks up SIL at her house that she shares with her BF. My MIL, tells me all my SIL tea and seems disappointed. But when we are at a family gathering, MIL will joke with SIL about cheating etc. SIL has even introduced the other guy to her siblings.
I told my husband, I dont feel comfortable with SIL taking our child for play dates anymore. I dont want our child around this drama or in SIL mix of troubles. If she wants to do that around her daughter she can but my child's feelings will not be played with. SIL tells my child that what ever guy she is dating at the time is his uncle. So I dont want that for mines. Also, I am 100% uncomfortable with the way his family (MIL) is okay with cheating and laughing about it. MIL likes to preach about good behavior and her kids do no wrong etc etc. But then enables SIL behavior and how it effects SIL daughter.
So again, AITA for keeping myself and my child away from my husband's family?
