<human>: Can you summarize the given text in a few sentences?

So...I'm having a bit of a crisis.  I've been with my girlfriend for three years, and like all couples we've had our ups and we've had our downs.  Nonetheless I love her with all my heart and want to marry her.

She, on the other hand, is ambivalent to marriage. Her reasoning is that marriage is just a piece of paper and that it doesn't prove her love or her commitment (which she points to the past three years as evidence of).

When she asked me why I wanted to get married, my answer of "Because I love you and want to spend the rest of my life with you" didn't seem to cut it (she argued that those could be achieved outside of a marriage), which left me rather speechless.  I don't couldn't figure out any rationale besides those two things.

What do you think, Reddit?
<bot>: Girlfriend doesn't care about getting married; asked me why I want to, I didn't have a reason outside of "Because I love you and I want to spend the rest of my life with you."
