Nasty/toxic Divorce advice

October 2020 my ex wanted the divorce and was already “seeing” someone. He TOLD me how the divorce process would work and if I got an attorney we would both lose everything. I didn’t listen, hired an attorney and filed for divorce November 2020. Ever since he was served with the divorce papers he has been making my life a living hell. We don’t have children so all we have to do was divide the assets and be done. Should have been simple. He lies, doesn’t produce documents, doesn’t show to court dates. It’s one thing after another and it’s so draining. I’m looking for advice, hope, anything. I have an amazing support system but nobody knows what I’m actually going through. They haven’t been through It. Thank you!
