Does She Love Me?

My girlfriend always lies on Mondays, Tuesdays, and Thursdays, and she always tells the truth on all other days. Unfortunately however, I don't keep track of the day of the week very well...

Here's what happened:

The day before yesterday she said to me, "I'll say that I love you tomorrow." The next day, instead of telling me she loved me, she said, "Tomorrow, I'll say that I could never love you."

But, today she said that she loves me!

Does she really love me?
