He’s acknowledging that you’re under a lot of stress, and he wants you to take the time to deal with whatever is causing the stress in your life, at which point, he wants to reconvene and decide if your relationship together is something you both want to pursue.
He’s basically asking you to take responsibility for yourself, which is a good thing. If you have stress that is impacting your relationship, then you need to deal with that stress so you can move on with your life and enjoy your relationships.
I hope that helps. Good luck! 🙂
