You've come this far, don't let that be for nothing. I once had a boyfriend who should have made a clean break but never did because he was afraid of what I might do. That caused so much hurt and damage to me in the long run. I've never been able to have a relationship since. At least there is honesty in what your boyfriend has done, I know that it hurts and your view of life without him is bleak but it is better than a relationship built on a lie. You can build a life that will be yours, it won't be easy but it is possible.
