I think he is feeling very frustrated and angry. He needs to be left alone.
I would advise you to immediately stop contacting him all together. No phone calls, messages anything.
You need to respect that he needs space and he needs to get himself back on track.
If he wants to contact you, he will. But otherwise if he doesn’t, leave it alone.
In the meantime focus on yourself. What do you want to improve on and get better at? What life goals do you want to achieve?
You can never force something that wasn’t meant to be.
