It sounds like he's still adjusting. Actually, I think what would help the best is for you to make sure to get in therapy and stay in it. You don't say what your diagnosis was, but if it is schizophrenia, even they can benefit from it. And also work with your psychiatrist about taking meds.
Obviously, being so jealous is not a healthy behavior for any relationship, and you need to get at the heart of that, too, I think.

Meanwhile, if you are okay with the distance at the moment, by getting busy with a job and new friends and not expecting him to be your all in all, I think that would also help. Everyone needs some space in a normal relationship from time to time, I believe.
