Just stop it. Put the big red stop sign in your head and stop it.
By time and space, H means at least a YEAR of time and space that only starts AFTER you let go of him and get your own life so that you stop putting emotional demands on him.
What he means is that after that much REAL time and space, he thinks he might be able to tolerate your company.
NO ONE on the planet knows if either of you would be interested in rekindling a romantic R three years from now. NO ONE. NO ONE can know.
So, quit worrying about figuring out something that is epistemically inaccessible. Leave H alone. Your M is over. The future is unknowable. Live in the present.
