What did I do?

So my ex and I recently broke up in thanksgiving. We were together for 2 years and we love together still. We are still in the process of figuring that out. But this isn’t the first time he “broke up” with me. I’m in my early 20s and he’s in his late 20s. A little background… we met through work but then mutual friends formally introduced us. Fast forward we both had recently gotten out of a long term relationship when we started dating. Everything was amazing and then it started to dwindle down. Resentment, no trust, communication. I support and love him unconditionally. And this whole relationship I’ve been the one fighting for it and his first instinct is to run away. He told me he never wanted to be in a relationship, he’s okay losing me, he doesn’t want to be dependent on me anymore. He’s making a big permanent decision based on temporary feelings. He’s come to pease with this break up and here I am in denial and refuse to accept this. I can’t put our relationship into words but this man saved my life and I won’t lie we’ve had our issues that I tried to fix but seems like I was the only man be fixing them. I gave him a suggestion of what if I move out for 5 months and we reevaluate everything then. I don’t want to give up my home. But unfortunately he didn’t agree to that. I need guidance.
