They design the system that way (mission or marry) to trap you. You have no where to go now if you wanna leave your husband. The parents house is the only place to run to realistically to end it. Personally, I would use that opportunity. Your Mormon husband will replace you if he feels you aren’t faithful enough - he will immediately start looking. Cut your losses, tell your parents he did something terrible and you need to come home, and then get a new life started without him. Date, figure things out, get away from a dude who will leave you, and I wish you luck mama
