Just power through till you file. Hold the course for now. File as soon as possible and work with your lawyer on specifics, since she knows your situation and the legal ramifications of it better than we do.
Set your phone to "do not disturb" for a few periods through the day to get yourself some peace. You're off having fun, you don't have to be at his beck & call just because somebody told him how it is.
Frankly, i wish someone had told my ex what a POS he was being. But no, they all had to come running to me with their stories and the screenshots of his Tinder profile and all that fun stuff. Be happy you have an advocate who loves you and speaks straight and don't worry about the consequences *of that.* Just get your paperwork filed and move on. You're going to be awesome.
