You totally did the right thing by protecting your kids from a situation you knew would be hurtful for them,
, you did exactly the right thing no matter how your mom and dad reacted. Glad your husband it so supportive and has your back.
I have a very toxic mother so I know how you feel. If yours is like mine, you can bet your butt she will treat you kids the way she does you,
and possibly even be cruel to them just to hurt you. I'm sorry you have to deal with this. Family is supposed to love unconditionally, but the toxic ones seem to enjoy spreading misery instead. BUT it sounds like you and your husband are great parents, and you're preventing them from being around people who could seriously scar their self esteem. You sound like a wonderful mom!
