Trying to get over a bad break up

I just broke up with my boyfriend of a year 3 days ago. I am having a lot of problems with this. I know it takes time, but the things that lead up the break up are really sad, and it was a bad one too.
Let me start by saying that he and I met at a bar last year. It was so great, we connected instantly! Everyone thought we had known eachother our whole lives, it was so perfect! It was really great up until a few months ago. He ended up quitting his job, and started to rely on me for financial support. That was hard on me, for obvious reasons. I was okay with that, at first. Then he started asking me for money, like every week he needed $60, and he gave me a bunch of reasons why he needed it. I didnt want to give it to him, but I did because I thought girlfriends should be supportive and help out when needed, he didnt have a job. He would pay me back when he could for what he took. Then he started to take more and more, and not pay me back. It was getting really crazy, then he moved out of his house and started to live with my parents and me. We said okay because he was starting a new job.
Here is where everything gets really crazy! I would wake up in the morning and find money missing from my purse, my credit card was missing, my parents found $400 missing from there room, and 3 days ago we found that my brother was missing a check from his check book. My boyfriend ended up taking a check with out asking, and forging his signature on the check which he made out to himself. That is the day that I said I was done with him. I later found out from his sister that he is a recovering herion addict who has been to rehab twice and started using again. It has been very hard for me to get through these past few days, and I wasnt sure if anyone had any suggestions for me. Any adivice will be helpful! Thanks!!
