My married crush admits she wants me...now i'm nervous
Ten years ago I worked side by side with a woman ("Jessica") whom I found extremely physically attractive from the moment I met her. "Jessica" is about five years older than me. We spent months working side by side, alone, on a special project. The more I worked with her, the more I realized just how much she and I had in common. We had similar childhoods, similar political beliefs, the same religious beliefs, similar tastes in music and a chemistry and a bond with one another that was unlike anything I had ever experienced with any other woman before or since. I developed a crush on her and a hard one at that. She was married, however.....so I said NOTHING!
I left the job a year later to pursue other opportunities.
"Jessica" and I found each other on Facebook two years ago and started communicating again. She admitted a year ago that she also had a crush on me since we worked together. Ever since then, she has been very, very flirtatious in her texts and e-mails.
Eventually, she started telling me how unhappy she has been in her marriage (and that she even left her husband right before she met me 10 years ago, but came back to him to make her very religious parents happy).
We have chatted often online and even met once at her place of business 11 months ago. I bumped into her at the grocery store a month later, but that was an unintentional meeting.
Things are getting really bad for her, in terms of how her husband is treating her, and she is implying that she means to divorce him (after Christmas, so her kids will enjoy the holidays, I assume). She calls me one of her best friends ever, but I somehow sense she wants to be more than my friend, based on some of her texts (we can't spend this Christmas together, but we will next year, we'll see each other fairly often after the start of the new year, I want you to be my boy toy, you are so good looking, etc.).
She also said her sex drive has gotten out of control this past year, but she still HATES having sex with her husband.
On the flip side, she tells me that she is depressed because of the way her husband treats her. She told me on a few occasions that she has been drinking too much lately. I sometimes wonder if her rational thought process has been ruined, either by alcohol or by years of emotional frustration in her marriage.
I believed 10 years ago that I was probably in love with this woman and those old feelings came back to the surface in a BIG WAY this past year  I want to be with this woman, but ONLY if she leaves her husband and ONLY if I know she is thinking straight.
What do ya'll think?
Do you think she is just looking for a friend? Or do you think she means to have some sort of romantic relationship with me once she leaves her husband?
I KNOW this doesn't look right, but I can't help how I feel about her!
How should I handle this?
