I'm so sorry. T&Ps to you and your mom and family. I do remember your story. Especially at time of stress with your mom, you don't need to be dealing with his antics. You deserve happiness. Hugs.
I remember your story. I had a very similar marriage with the infidelity. I'm sorry things have gotten worse. You will have bad days but being away from him will be easier. Take it day by day.
I'm sorry about your Mom. You are really being thrown some punches in life, please take care of yourself. Get a lawyer and a therapist. You will need somewhere you can go and talk safely about all the things you are going through. Not to put more on your plate, but if you were still having sex with your stbx you may want to get tested.
I was thinking of you just the other day - I'm sorry things have gotten so badly but I really hope that this is a time you look back on just to see how far you've come.
