I agree with Wendy. Get a lawyer and an accountant asap. This is not okay. He’s stealing your money and not letting you on the cell,plan because he’s probably doing something shady. Because if he trusted you and you trusted him you’d have nothing to hide, you’d be on the same page and equal partners. Your post tells me you’re not at all getting your equal share in anyway. This is a big wake up call that he took…is your share half, $42,500? from you!! Why do you let him walk all over you and take, take, take?? He’s not nice, generous or a good partner to you.
Why have you been with someone for ten years who treats you this way? Lawyer, accountant, breakup and leave. You’re not paying your fair share, you’re paying more than that. It’s not fair at all.
Also I bet he’s being shady on his phone and blames it on not being able to trust you with money. I hope I am wrong.
