It's hard to think of quotes that relate to marriage in general but I like these quotes since I think they show the strong relationship/marriage Peter and MJ share.
MJ: "Maybe the rest of the world thinks marriage is something to do between other marriages, but it means something to me. Youre my partner and my husband and I love you. This is our life."
Peter: "I want to give you the life you deserve to have. I want you to have everything you ever wanted --"
MJ: "Then like I said: youre out of your mind. Because the only thing Ive ever wanted
is you."
Peter: "Its not just that I love you, MJ. I need you."
MJ: "You dont need me, Peter. Youve got all these powers, you were out there doing all these things --"
Peter: "Youre wrong. I can do "all these things" because you believe in me. Because you give me the strength and the will to get them done. Everythings easier when youre there and harder when youre not. Without you, nothing works the way it should. But when I know youre there, in my life, I feel like I can do anything, MJ. Anything."
Peter: "When you live with someone day after day, its easy to forget sometimes who they really are, and what they can do. Then when you see it, when youre reminded just what they can do
its a revelation. People see me swinging around skyscrapers and they think Im pretty special. But its not me. Its her. Its always been her."
