Even hell can get comfy once you've settled in-An Oliver Sykes/BMTH fanfiction

What do you do when you're beyond in love with someone? They're your other half, they know everything about you and they still love you unconditionally? Be with them, right? What if it's not that easy? What if they aren't exactly healthy? Physically they are, but mentally? Not so much.
Now what are you supposed to do when they get out of the mental hospital they've been in for the past 5 years? Are you supposed to be with them then? You'd assume yes, but what about when this all happens when your girlfriend of a year is already moved in with you, apart of your life, and even better is pregnant?
Oh yeah, and no one even knows she exists.
This is exactly the situation Oli's dealing with.
Should he drop everything else and be with her like they've always talked about and be happy? Or man up to his responsibilities and have to question what if for the rest of his life?
