OK

So she's definitely lying to me. The question now is, what is she hiding? It could be mild, or not serious at all.

Here are my guesses, from tame to worse.

1.) Maybe today she was really just tired and lazy - and didn't want to tell me no, so she made up this little lost phone story. Too predictable!

2.) The last 5 days have had a similar pattern of little phone activity at night, so maybe she is back with her ex - but she has decided to keep me going because of things I can do for her that he can't.

3.) Maybe she's seeing another guy, or more than one guy - who knows how her world is when I'm not there.

All of these questions indicate that I can't really trust her. And it's not my own lack of trust in her - she has given me reason to not trust her.
