Recently moved out of the marital home (UK) to live in an apartment which is jointly owned with my wife.

I've met someone and want to spend quality time with them at the apartment. However my wife insists she not only has the right to enter the property at any time but also wants to stay randomly, expecting me to go back to the marital home while doing so.

I'm looking to file for divorce though this may take some time. What are my living options in the meantime?
