My FP has given me an ultimatum; either we break things off peacefully or he will end up ghosting me within the next two months. I am currently in law school and this is so painful. I have so much work to do that I barely get to spend any time with him as it is, and now I have to worry about him leaving.

I tried leaving him multiple times because I care about him and want him to be happy, but I always end up coming back. I can't imagine my life without him. The idea of him meeting someone else or doing all the things that we did together with another person is killing me.

None of my usual coping mechanisms work. I tried to meet other people, I tried to numb myself with alcohol, I tried to turn off my emotions, I tried hating him, I tried being more rational and thinking that this is for the best, nothing is working. Nothing. 

I know that we'd be able to have a happy and healthy relationship if I got treatment, but he's not interested and I don't have that much time to fix ten months of damage. 

I don't have any support system outside of him. My instinct is to run and move elsewhere, start a new life and cut contact with everyone, so that I don't have to go back to the life I had before him.

Does anyone know how to cope with this?
