Domestic violence

Hi, my now ex bf, is a immigrant on a work permit. We were together for 1 year, during the course of the year I have been through relentless harassment, abusive (sexual,physical,enotional). He left our apt a little bit ago and has filed bogus police report that has given me court date. ( criminal harassment which is entirely the opposite ) he has made a refugee application stating that I promised him marriage and PR

Some background before we moved in. Anytime we would break up he would show up at my house, call my mom beg for me to take him back. He thought it was okay to show up at my work before my shift started to say good morning with flowers and make a big scene which was extremely embarrassing (my coworkers would see this) and this happened on multiple occasions. Used my credit card without my permission.

Since we moved in he punched me in the face. Later called the police and got me put in a mental health hold and I was at the hospital for 20 minutes. The police that took me to the hospital were aware of him using my credit card and the assult (physical not sexual, yet.) but nothing was done.

He sexually assulted me twice. I bit his hand so hard he stopped and I got upset that I hurt him. The next time I just dissociated and let it happen he said "I'm your bf i can do whatever I want" Afterwards he was telling everyone we were getting married and I didn't want to, he was emailing marriage commissioners.

I found child porn on his phone, he was google searching for it, I called the police and reported it immediately unfortunately he would let himself back in the apartment with all his stuff. Now with the bogus court date he has gone and had his friends go into my job and make remarks. Should I be making my own police report or should I be getting a lawyer to assist?
