I am not going to tell you what you want to hear, but what you need to hear.
The relationship that was is over. It will never return. Don't hang onto it any longer. You were young, and most of those relationships do not last. Its time to mourn its loss, heal and move on.
You two will always be a part of each other because of your child, but don't be miserable trying to make it work.
You both have some maturing to do. Let the changes happen. Embrace them, for you and your child, not anyone else.
Your changes have to be for you. They are a good start. Stop hanging on. He is moving on, I suggest you do the same or you will be a miserable doormat.
Your situation added to his condition and need for medication, getting back together will only bring it back. Find your own happiness. Don't make him be the key to that happiness, it lies in you, not him.
This is the time to learn who you are and what you need and want for happiness. You have a child to consider too. Remember, what you do and how you let yourself be treated effects them and helps determine how they allow themselves to be treated and treat others.
Let him go do his thing and you do yours. Soulmate is a nice term too easily thrown around. You had a connection. Its gone. Remember it fondly, but don't hang onto it.

It's worth a shot and I think you're on the right path. Regardless of what happens that is not in your control. What is in your control is what you make of your life for you and your child.
He has to want it for it to happen and only he knows that. So you need to just talk to him and lay it all out. To be honest he might want to have some freedom before he comes around. That's something you need to ask yourself, whether or not you can deal with that.
I'm NOT condoning sleeping around but reality is you both got together very young. You already have a child together, and add the stress from all of that. You both weren't even really grown emotionally. Your both at the age where you're starting to know yourself and what you want for yourself.
So your choice is to continue to better your life and choose how patient you are with him. Choose how long you want to work it out. Weigh it all out and remember that only so much an come from your part. He has to want it and act on it too. Regardless of what happens you have turned over a new leaf and you will be okay and happier in time.
