How to help my mom

So my mom and dad have been having marriage problems for a very long time. They had me and got forcibly married at age 20.

They just told me a few weeks ago that they’re separating and then today she told me that she threw him out of the house after a huge argument.

I’ve witnessed their arguments and fights ever since I was a baby so I’ve been there.

What can I tell my mom to console her? Because she’s going through a very difficult time.

Thank you in advance
