The last EX g/f who lived with me called the office one day at 5:10 pm. Now, I only live 3-4 minutes from work.

"Why aren't you home yet?" The beginning of the end.

How long have you known her? Lived with her? If it's a new relationship, it'll likely get worse. On second thought, new or not, it'll probably get worse, at least in your own mind. That's all that matters.

Good Luck with it.
