IM 4MNTHS PREGO AND JUS LET GO OF AN ABUSIVE BOYFRIEND HOW DO I COPE WITH THIS?

I BECAME PREGNANT FROM MY PARTNER A MONTH AFTER WE MOVED IN TOGETHER. I AM NOW 4MNTHS, HOWEVER AT FIRST THINGS WERE GREAT HE WAS ALWAYS HOME, LOVING AND CARING. THEN ABOUT A MONTH AGO HIS AMBITION FOR MONEY BEGAN HIS WHOLE ATTITUDE TOWARDS ME CHANGED, HE CLAIMED I WAS ALWAYS ON HIM AND HE NEEDED HIS SPACE. AFTER BEING IN A MENTAL HOSPITAL(ME) FOR PRE-NATAL DEPRESSION I UNDERSTOOD TO JUST LET HIM BE IN TILL THE DAY HE LAID HAND ON ME. I MADE A POLICE REPORT, IN WHICH COPS DID NOT DO MUCH ABOUT IT. I ENDED UP TAKING HIM BACK IN OUR HOME I FELL FOR HIS LIES. NOW I UNDERSTOOD THE ONLY REASON I WAS PUTTING UP WITH ALL THE EMOTIONAL ABUSE WAS BECAUSE HE WAS PRETTY MUCH SUPPORTING MY TWO BOYS 3 AND 2 AND MYSELF. WELL JUST RECENTLY HE LEFT ME STRANDED FOR 2DAYS WHEN I WAS ABLE TO COME HOME I FIND HIM WHAT APPEARED TO BE DRUGGED. SO I CONFRONT HIM AND HE GETS DEFENSIVE I CALL THE COPS AND GETS INCARCERATED FOR VIOLATION OF PAROLE. IM NOT SURE IF HIS PAROLE PICKED UP ON DOMESTIC VIOLENCE REPORT. HOWEVER ALL THOUGH I KNEW I DID THE RIGHT THING BY LETTING HIM GO I FEEL SO MUCH GUILT. I DO NT KNOW HOW TO DEAL WITH ANY OF THIS. I DO NT KNOW EXACTLY WHERE THE GUILT IS COMING FROM BECAUSE I KNOW I DID WHAT HAD TO BE DONE. NOW I OF COURSE WILL CONTINUE MY PREGNANCY WITH OUT HIM AND IT'LL HURT BECAUSE GOD KNOWS IM TRULY IN-LOVE BUT I ALSO KNOW I DIDNT DESERVE ALL THE ABUSE ESPECIALLY IF HE HAD NO CONSIDERATION THAT I AM CARRYING HIS BB. I NOW LAN TO MOVE BACK IN WITH MY PARENTS ASAP AND FINISH SCHOOL BUT I NEED ADVICE ON HOW TO COPE WITH THIS SITUATION. IT SCARES ME AND HURTS TO KNOW HE'LL PROBABLY WANT NOTHING TO DO WITH ME AFTER THIS AND WONT BE THERE EMOTIONALLY FOR HIS BB EITHER BUT SHOULD THAT MATTER? WAS I WRONG FOR CALLING THE COPS JUST BECAUSE.? HOW DO I GET RID OF THE GUILT????
