Any advice on how to detach and let the fuck go of a relationship? 

I’ve been in mine for 3 years, it’s never been all that healthy but it’s gotten worse lately. He was gone for a week on vacation and the whole time I was thinking “I’m ending it when he gets back, I’m fine alone”. Well he’s back and now that we’re face to face I’m not fine and I can’t do it. I just want to be normal and tell him I’m done, walk away and feel better and stronger. My friends do it all the time and I don’t understand. Every time the moment is here I panic about the thought of being alone. I’m very unhappy in the relationship but I feel too attached to him and having someone around all the time (for 3 years!!!). I feel so trapped it’s suffocating.
