aio my wife cheated and i told her parents

My wife told me I am overreacting because she cheated and I told the entire family about it. She is embarrassed about it because her mother said she is a skank and a lowlife. I feel like I overreacted. I am filing for a divorce and speaking to an attorney about the whole situation because she also had another child and did not seem remorseful.

Update: After reading all of these comments I feel good about my actions. It was a little immature on my part as I am a grown man. For context, no the third children is not mine but that’s a whole other discussion. Although the third child is not mine I was under the impression that the child would come out to be mine turns out she cheated,got pregnant and lied. I still want to be in the child’s life because every child deserves a loving father, but as far as a relationship with her it’s over thank you all for the advice. ✌️
