Anywhos, to the details. It was set in the future, it had 2 main characters, a male and a female, with a relationship between the two. The female ends up in some sort of army piloting a space-craft mech who is eventually sent off into space, while the male character stays on Earth. The female character goes deeper and deeper into space and the male continues to send messages to the female, with each message taking longer and longer to send due to the vast distance from Earth to the space army's fleet. The male eventually has some sort of emotional breakdown, I think. The last thing I recall was the space army finding an hospitable planet, similar to Earth.
Yeah pretty dodgy description but I watched this like 5 years ago, so I can't be doing too bad if I can give that kind of description
Many thanks to the person who can figure this one out!
