"It doesn't mean you have to do that again, MJ. You don't have to be alone here." Peter says, actually pushing back against the idea. The urge to apologize is still there, but it doesn't win out just this once. There will always be a part of him that loves MJ, and that translates into trying to stay in her life.

He seems on the verge of arguing that at least somewhat, "I'll still always worry about you. I understand you... don't want to see me for a while, but, I don't want you to be alone out here."
