<human>: Summarize the given text in a few sentences.

We've been together for 9 years, lived together for 8 of those. I moved over 1000 miles to live with him and we still live here. We've been through a lot over these years but always remained strong. I always considered us the perfect match and know we'd face everything with success. The last 8 months have been terrible. Things have changed. He lost interest in me and now we're in a situation where I know we will break up. It's like the break-up started 6 months ago and none of us does it even though we know it will happen. I am moving out and we say we will stay together but be seperated. I know this is only a disguise for slowly growing apart. 

I am terrified of the thought of not being with him. I do not want this. I know it can't be avoided as he does not want to share a life with me but I wish he would change his mind. I do not know who I am if I am without him. This sounds a lot like a teenager breaking up with someone and being "overemotional" but I have no family here, we got mutual friends (his friends) and I simply don't know what to do without him. I always thought this slow break-up would make things easier but tonight I panic. How do you deal with break-ups after such a long relationship? I am terrified.
<bot>: Been with spouse for 9 years. Know we will break up sooner or later, probably sooner. How the hell does one continue living after losing someone you spent a third of your life with?
