"How can you promise someone you'll feel the same way forever?"

You can't-- not really. But you can by promising that you'll always be there, and that you'll stand by them through thick and thin, make their battles your own, share their tears, share their laughs, share their memories and create more together and by promising to belong to them and let them belong to you.
The trust and emotion will just come naturally. But "feeling the same way forever" at this point won't even be possible-- your feelings will instead run deeper every day.

Don't be afraid to argue, to fight, to cry. Don't be afraid to joke, to smile, to laugh. Mess-ups aren't fun but then you have Clean-ups.

Always-and-Forever can be near impossible... but that's why you have No-Matter-What.
