Marshall: What if you decide to go be a painter and then you realize I don’t fit into your life anymore, and three months becomes forever? Can you promise me that that’s not gonna happen?
Marshall: ‘Cause if you can’t promise me that, we should just break up right now. I’m not gonna wait around for three months just to have my heart ripped out.
Lily: Marshall, I love you.
Marshall: Can you promise me that that’s not gonna happen?
Marshall: No, Lily, we cannot pause this anymore.
