I talked to someone last night who was in the stage of her relationship and I remember being there. When you break away from him you will start to heal. Eventually you will sick of being sick right alone with him and you will pull away for good and then one day you will take a deep breath and realize it's been a while since you breathed.
In your time............you'll be done with this mess. Hopefully soon you'll break off the conversation all together. That's where the healing starts.
