I have a urinal in my living room and my new girlfriend cannot handle it - she says she will leave

TL;DR! : I have a loo in the living room , not intentional , how can I stay with her , its just there.

I bought my house from a elderly man and that is why my living room is fitted with a urinal.

I never removed it and did start using it , my friends also have always used it , I have always kept it really clean and put cubes in it to try to keep a mint fragrance in the room.

Fast forward to where I am now , a few months ago I met a wonderful , beautiful woman , I really do like her.

When she first came round my house , I covered the urinal with an old curtain which I drapped over it.

It was not a problem , we spend the evening watching tv , had dinner in the room and it was not mentioned , it was not an issue.

A couple of weeks later I had the guys round for a PS4 session and whilst I was outside of the room one of the boys pulled off the curtain and started using the urinal , my girlfriend walked in from the kitchen and saw him , she was horrified , could not believe what she was seeing , after a really heated argument she left and it took a lot to explain things , but I did , and weirdly it made us closer.

We are now two months into our relationship and to skip forward I am fully using the urinal 24/7 , it is my prefered loo , I dont like having to walk upstairs. This has become a real problem with my girlfriend , she does not want to come over to my house anymore and will only meet up at hers , I am totally into her and do want it to work but am not into having someone else run my life and dictate that I can only come over to her house.

I really dont want to change my house for her , I would like to hear from a womans perspective , is it something a woman would just adjust too over time.

thanks
