Hi Aimee.
I am sorry to hear of your gf's ex.
As for getting out of your head - I think most of us did that as another means of escape for the world that scared us, or angered us, or whatever - I think the move into the real world comes naturally when we stay sober and find that life, as it is, is actually not that bad.
Congratulations on 30 days! That's a great achievement
