I’m guessing that you have the chance of seeing him in person, because if not, if he’s blocked, it’s impossible to talk otherwise. I don’t really have that option, I can only contact him through the phone, and I know he won’t answer, so I’m trying to find him in person, but it’s not easy.
You said you wanted something to change, I don’t know your situation in dept, but you can be that something. He’s just one part of two, you can change as well. You’re a piece of the cycle; if you change, the situation is already different because you are. Even if he’s the same, you’ll perceive and manage it differently.
I think focusing on yourself doesn’t just mean doing your work, but also means stopping the “he’s ready, he’s not ready, he has to do this or stop doing that” thinking. Even if we share energies, forget about him and embrace your power, what do you want, what do you need.
You want to talk, then go talk, I cannot promise you it’ll turn out the way you want, but you did something. If you wait until the situation is right, you might be waiting forever. There’s a threat about how not doing something might keep us trapped: “Divine Timing” for Twin Flames Might Be Keeping You Trapped.
This is just my opinion, you can see things different, every journey is unique.
