Peter wants to ask Alec to stay because every time Alec goes, he worries. But Peter knows he can't ask for that, because it'd be selfish. So he doesn't ask.

Peter takes a breath, his shoulders rising a little with the act. He's starting to feel less teary; his eyes are burning less than they were before. He stops looking at the floor and looks up at Alec.

"Do you think you're going to ever be okay with this?"

Peter isn't just asking for himself. Selfishly, yeah, he wants Alec to be okay with this because he doesn't want to worry. But he also wants Alec to be okay with this because Alec deserves to be. He deserves to be comfortable with not being along with being able to make his own choices with being able to think his own thoughts.

Sometimes, he thinks Alec thinks he doesn't deserve that.
