<human>: Hi Reddit,

We've been in a relationship for over 4 years. Over 2 of those we've been living together. We're both 30 and just recently she's been having a lot of trouble without have her own space.
Only a handful of months ago we both would have agreed that we were going to get married / have kids down the line, but there wasn't a rush for all of that.
We live in a 2 bedroom apartment. Not huge but not small. We've always been good at creating our own space.
We've spent the last few nights sobbing with each other because neither of us want "us" to end.
She doesn't know how to fix the feeling inside of her. She says her gut is telling her to move out.
I can't see that ending in a good way (ie. She moves back in and we continue down the relationship line)
Has the "move out but stay together" tactic worked for anybody here? Is it just a slow way to end a relationship?
Is there any other way to get her the space she needs?
We both profess to be the love of each others lives. Neither of us want this to end... but... is it ending?

Provide a brief overview of the text.
<bot>: Girlfriend (of 4 years) and I still very much love each other, but she needs space and wants to move out. Do we have any hope of salvaging the relationship if that happens?
