My sons dad applied for our sons family allowance

Dawnn

He stated that my son was with him for atleast 5 months so now I owe CRA almost 3000$ for all those months i received his money and he received that back pay, my son been with him one month til he came home, but even then I used that money to get him everything he needed, and then he was not allowed near me or our son because he threatened to smash my sons head in and threatened to go shoot up my family and crash into their house with his vehicle, and hit me in the belly (I was pregnant with our daughter at the time who he has never met after that) all those threats so i wouldn't leave him or try ask anyone for help and wanted me to be alone.. but obviously I fled and got help because now hes not allowed to come near us.. but why this? Idek what to do or how to correct this, I've applied for a parenting order.. so hopefully it all goes over quick because I want to leave this town, i wanna meet new ppl.. I'm so tired of arguing and being sad all the time.. I want my happy ending that everyones getting after leaving abusive relationships with a guy who loves her children as much as she does.. just blah.. rant over.. just needed to cry about it for abit and get back to handling it..
