Hello....
It seems to me that you should just concentrate on the other lady and leave this one alone. Beleive me I've been friends with many people online over the years. And for the most part I'll tell you that most of the time they are " drama queens" and people just looking for attention. and really not friends when it comes down to it.
One exception is here on this forum, beleive it or not I've only run into one person that i began corresponding with that i got a bad vibe from, and found many lies from e mail to email, therefore I stopped e mail and contact. I follow my inner gut I got the feeling that things just werent quite right.
