Yeah, I saw her that night she 'advertised' on FB, always good to see her in BKK when she's up. 
Like any person I think Nancy would like the dream future with someone she can be close to and is not shy about wanting to find the one (see cabbages and condoms posting - lol) - the fact that she moves around a bit and has nice times away I think pushes the rumor mill into overdrive by all and sundry. Like when she takes off to Oz, or to a nice LT resort trip or back home.
So far as I know she has never left La Bamba or intends to until her future is secure with someone.
It's her work, her life and her lot still but she continues to be an incredible person in every respect when you meet her or spend time with her. 
So, La Bamba remains her work place and you will usually find her there - just be sure to also connect with the La Bamba Team via the forums before you fly in specially and check she's going to be around.
