I also.don't think this would warrant 8 hours of argument. I would not.be on a polyship with someone clearly so jealous. It wouldn't be worth all the drama. If I loved them and wanted to be with them, then id just be mono with them and be sure my next partner. Isn't unreasonable and wants the same thing I do.
