I'm very sorry. But I'm not surprised. From what you've written, your WH has never seemed willing to "do what it takes" and you didn't lay down a boundary.
You know what you need to do. Detach from this f*tard and protect yourself and your DD. Give him back his crappy phone....you have all the evidence you need.
If you are comfortable with your L, go and file. If you're not sure, keep shopping. There is no rush.
