Actually, not quite. In case you didn't know, the house was purchased before they got married. This video below (screenshot) was from June 2015. Tanya was all excited filming outside in their garden (if you can call it that) for the first time. They got married in September 2015. So yeah, if the house was solely in her name, she doesn't need to pay him a thing as it was acquired pre wedding. Hermione Chantal (Youtuber) purchased a house while engaged, they later split up, she kept the house to herself as it was solely in her name. Smart cookie.
No need to get all worked up tbh. I'll continue saying what I want aka Tarn kept the house just as you can say whatever you want.
