I’m going through a divorce

Hi, my wife and I are going through a divorce. We own a house a together and the interest rate is 2.5%. I have a few choices:

1) Sell the house and we split the profit 50/50.

2) She doesn’t want the house anymore; she wants to live closer to her family. Can she stay on the loan with me, but sign something to say she’s not responsible for the mortgage anymore, that way I can keep the house with the low interest rate. If I’m keeping the house, I will have to pay her 90k. I don’t have that much money right now. What can I do to find this money? I make around 125k per year so I don’t know if I can pull a loan for that much.
