Just keep documenting these events for your court date with the judge. Including that crazy text the other day.
Your ex is truly an *******.
He reminds me a bit of my dad who has always made promises he rarely keeps. That dynamic has been one of the hardest things for me to overcome as a person and has been a HUGE reason I have dated men who do the same. It took me a long time to realize that. My suggestion is for you to talk honestly with the girls as they get older and re-enforce your own honesty and steadfastness with them. They need to know they can trust people and people will keep their word.
Sorry for you guys.
