My wife gets along great with my mom and that says a lot about my wife because my family can be a royal pain in the butt sometimes. My ex wife hated my mom so much that I ended up estranged from her for almost 10 years. That was a really sad time.
I know my family can be a handful, but my mom is a really good person and I appreciate that my second wife goes out of her way to have a good relationship with mom.
