He broke up with me because of his childhood trauma coming back into his life. was that a valid reason for us to breakup?

Me and my ex had been together for almost 2 years and it was a healthy relationship. Arguments here and there but we resolved them immediately. He had something come up that he says, “ made him empty and emotionally and mentally confused.” And so he broke up with me because he said he can’t be the guy I need right now, but he claims he still loves me and wants me in his life, even though our communication is zero to none. He doesn’t want to say if there’s a chance of us getting back together in the future once he gets himself better just to not give us both false hope. I message him now and then making sure his mental is alright but he never seems to answer me as if I’m muted on notifications. What do I do?

He gets in touch with me maybe once a week but the conversation is very minimal.
