Relationship drama

Ok so me and my ex were together for 3 years. In may I got the implant and my emotions started raging I was getting angry at every little thing I was popping up to where he was at trying to fight and eventually he called the cops on me because he didn't want to fight me. We broke up at beginning of June and It took me a while to get over because I thought it was the person I was going to be with forever. Fast forward to 3 days ago he texted me saying I just want to make sure your okay and your happy, and I was but ever since hearing from him it only made me want him back. I'm not sure if I should just let 3 years go to waste for 2 bad weeks or if I should try to get him back. The issue is I know he misses me but Im not sure if he would be willing to try again. I really don't want to get my feelings hurt but I also don't want to see the person I love get with someone else. What should I do?
