Welcome and I'm sorry,

We step moms have to take a strange amount of abuse considering we didn't pick our SO's ex.
I for one will go on record, that while I knew my husbands ex was unpleasant from the time we started dating, I had no idea she would turn out to be kookoo for coco puffs.
It was( and still sometimes is) almost unbearable, and if it weren't for the fact that I'm just too stubborn to let her win by chasing me off, I don't know how I've lasted this long.

I've been though it all police, CPS, restraining orders, and all forms of abuse accusations have been loped at me but no one ( thank goodness) believes her outrageous lies. Even when the investigators come right out and say " BPDmom made it all up to set bravhart up to look like a bad person, she still claims it's true.
I've had some pretty rough days, but I can honestly say the advice and support I've gotten from these good folks on this board have made it better. Don't be afraid to reach out and ask for help, advice etc., someone on this board has dealt with the same stuff as you and can relate.
Welcome and take care of yourself
