How long have you been doing the 180? Do you think she's noticed? Why are you getting the apartment when she's the one who asked for the "change"? Why did you put down the apartment deposit if you're still debating on staying in the house?
Need more info!!! Why, after 10 years is she randomly done and needing a change? Did she give you any other explanation? If she complained about you never being around... being busy and leaving are not the best ways to DB.
What do YOU want?
When you are happy as an individual, you are in a better position to determine whether a partner enhances your happy life or weighs it down.
