Yes it is! He literally left their wedding to go looking for you, Will! That's exactly what...
Brady: What are you going to do, Will? How do you see this conversation going? "Gee Paul, thanks for saving my mother's life and falling out of that window and nearly killing yourself. Oh,by the way, I've got my memory back, so see ya. Don't let the door hit ya in the ass on the way out."
Will: Brady, come on, you know it's not like that.
Brady: Then what is it like? How do you see it going? You gonna sit by his bedside and let him down easy and he's gonna be okay with it and say "Hey, no hard feelings"? I got news for you, Will. It's not gonna go that way. There's only so much a man can take! Sonny used him when he thought you were dead, but as soon as he found out you were alive, he dumped him.
Will: No, Brady, that's not true.
Brady: Yes it is! He literally left their wedding to go looking for you, Will! That's exactly what happened. And you're doing the same damn thing. You know what Paul is? Paul's a placeholder for you for when you got your memory back.
