Он меня душил, держа ребенка! Что делать, если бывший абьюзер преследует и угрожает?

Around 2 yrs or more i left an abusive man he strangled me while holding my little 1 yrs old in the other hand standing against the wall and then while i was laying down and he held my baby in his lap strangling me again towards my left side on the neck. Now he keeps messeging me because he is video calling my daughter so he think he can send me stuff about being careful who watches my child because she told him she is in daycare. I messeged him reminding him he stragled me while holding her and that my kids and i are safe because i left and he is the one i mostly fear around my children told him to please stop sending me stuff. Now he is writing all kinds of exuses how i imagened everything.....did i imagine the pain too?
