Look, I'm sorry things suck and we can work out a time for you to get your stuff but we aren't together so I really just can't be the one you lean on to fix this stuff anymore.
It makes sense to me?
I agree with Sam, right sentiment, wrong way of saying it. JUST STICK TO BUSINESS. Tell him you don't have time to take his phone calls and that he needs to respect your privacy (that goes for work as well as home!) Then set his phone number on your phone to mute so it doesn't ring or buzz when he calls. You miss a call or two or twenty from him? GOOD. THAT will send him the message that you're not his personal assistant. You do understand that every time you get a call or text from him it sends you spiraling down all over again? Yes? So why let it happen? You can put an end to that real quick.
He will lean on you as long as you respond. It's his way of controlling you. Once you quit responding, he will stop it.
