Sorry for your pain. I completely understand and have been through it. My ex did the same thing, more or less. It lasted a few months. Gotta remember he is not in a healthy state and will not sustain a healthy relationship with her or anyone. Remember how it was for you? Ask yourself if you really want to spend the rest of your life doing that same thing?? The more you take care of your needs and focus on healing yourself, the less it hurts and you'll see the situation with a new pair of eyes.
