I think this is about a relationship that isn't going anywhere. They can't be together, for whatever reasons, and there is too much of a risk.

You've got to get better; it's all in your head = the way the turmoil is causing them to break. The way one questions how the other feels, because they're desperate to know they are loved by the person. The other one is saying either 1.) It's all in their head that they think it could work out or 2.) Their paranoia over wondering what the other is feeling is driving them crazy.

Live through these letters or forget it all together= means they can keep at this fruitless facade, risk hurting others so they could be together. They can try a friendship from a distance, unable to fully let go of what they both want. Or they can accept reality.

Months don't matter/days I can't take When the hours move to minutes and I'm seconds away = the well-known feeling of how slow time goes by when you're missing someone. They know once they get over the initial pain, it will be bearable. But the minutes are excruciating. And I think the seconds away could mean from running back to the person. From picking up the phone. Or from doing something dumb like getting plastered. Or from simply losing their mind.

Just ask the question, come untie the knot = he wants to give it another try. Maybe it's not rational, but he wants to open that door back up and immerse himself in her. He's hoping she will feel the same, and know that even though it'll get them nowhere, it's ok to give in.

Retrace the steps as if we forgot = meaning experiencing their love as if it was fresh, without all the risks, restraints, and negativity that has led them to where they are now. Just going for it, like old times. Forget reality.

Try to avoid it, but there's not a doubt and there's one thing I can do nothing about = he knows it's not for the best. He knows he needs to stay vigilant. He knows he has to let go. But at this time he also knows it's totally worth it to go around one more time. But she's not so sure, and he can't make her give in. He's ultimately powerless if she says no.

When all that we need is just a reaction = this love is doing no good. But if she would accept his proposal to go around again, it could maybe work this time. She just needs to answer him. She just needs to say she's still there. One of them needs to speak up.

There's too much to ask for when there's no attraction anymore = on the surface this probably means that she isn't attracted to him anymore and wants to end the relationship, but also I wonder if it means something else....I'll come back to this thought.

Chasing our dreams is just a distraction = how it's pointless to live in a fantasy world where they can be together. Holding onto each other so tightly is creating holes in their individual lives. Or he's saying if they could just focus their energy on something other than each other, then they'd see there's more to life.

I want to remember what I know that I can't to back = he wants the feelings of acceptance to stay. He wants closure within himself, not necessarily from her. He wants the urges to subside and to focus on reality. It hurts too much to stay in this cycle.

(I might come back and clean this interpretation up a bit.)
