Is she really overseas right now?

I met a nice woman on POF several weeks ago.  We've been seeing each other a couple of times a week.  Nothing hot or heavy yet, she wants to take it slow.  She's told me that she's a widow, that her husband died 5 years ago and that she still has their house in the U.K. north of London, near Manchester.  She just left to go there for two weeks.  Said she has to do more paperwork and check on the house, as she's going to sell it.

All sounds a little over the top.  She calls me from her cell phone most nights.  My problem:  Is she really there?  How do I know if she is there or just trying to avoid me? Is she really overseas right now?
