Just throwing something else for you to think about into the mix as well...
You don't know this person. You don't know what is going on inside her head, what her motivation is, or what she is capable of doing.
That would make me very, very wary.
I know it sounds a bit over dramatic, and chances are everything will be fine. But I wouldn't want to take the gamble.
I remember XH got emotionally entangled with a work colleague (this was a good while ago, a few years before before the PAs). I reckon he was toying with her a little bit, but she considered it to be more (much, much more) than it was. She ended up stalking him for almost a year. I can't begin to describe how stressful it all was. Unbelievably stressful.
She had her own idea, in her own head, about what it all meant and what was going to happen between them. She's be emailing him, texting and calling, even in the middle of the night. And it was constant.
Please don't run the risk of putting yourself in that sort of position. You've got other things to be thinking about in your life, more positive, constructive things that you could be focussing on.
