So sorry you’re in such a tricky situation. I’ve rewritten my post so many times and cant come up with anything truly helpful. I waited too long for our agreements to happen, that it ended up taking its toll on me and the kids ( he just made excuses and caused delays and placed blame!) Mediation could possibly be a route, or a waste of money of he’s just pretending to agree but drops out at the last second! Definitely worth talking it through at a professional about your specific case, you need support. I truly feel for you, sending massive hugs, you’re doing a great job, your kids are lucky to have you x*x
