Hey all. I thought I'd just say thank you for any comments and offer an update. I did indeed build up enough courage to end the relationship. We lived together for a further 2-3 months before moving out just before Christmas. Her binge drinking went up and down depending on her emotional state, but hopefully this most recent change will be beneficial for her. Watching someone you love destroy themselves with alcohol is one of the hardest things, but I'm glad that I have a little freedom now and can assist as a 'friend', rather than a partner who was unable to escape the situation. Witnessing someone first-hand struggle with alcohol is a gruelling experience that I wouldn't wish on any couple.
