You are in a stronger position than you think here. She cannot stop your partner from moving in because you own half the property. If / when he does who is going to want to rent a house with a married couple. After getting hubby in, I would stop paying mortgage, and force a crisis situation. Her hand will then be shown. Her most likely move will be to agree to sell.
I'm assuming that you would agree to sell if she would. Her not agreeing to sell is way out of order. As a consequence, she is attempting to bully you into doing what she wants. You need your equity to move on etc.
As previously mentioned, you also have the option to move legally. I would accept that things are past simple rectification and act accordingly.
