need to vent

Ok my husband is currently in nor cal for work and is telling me he has decided to move out there. Knowing I can't go with him unless it gets approved by a judge due to my custody agreement for my daughter. He is also saying that he is going to take our son with him and I will see them Saturday night til Tuesday night. Where he wants to move is about 5 hours away and he doesn't get off work on Saturdays til about 6 or 7 at night. This is giving me anxiety. I think he's joking cuz I don't think he would make a decision like this without talking to me first but I just feel myself getting upset at the thought of him doing this. He says he's already put in for the transfer with his work. I'm trying to calm down but I can't. I know I'm being dramatic. Just needed to get this off my chest
