Why is your opinion of yourself dependant on whether he loves you or not, whether he was using you or not, whether you were his ticket to keep drinking or not? Is your worth as a person based on what others think of you, or what you think of you?
And why do you need to believe that he doesn't want you to see him like this in order to be positive? The guy is getting help for his addiction. That's reason enough to be positive in my book. Especially when it's someone you love.
