Why does my married ex try to get in contact with me once she finds out I have a possible high paying job and am close t

She may have found out from a mutual friend or the type of possible career I listed on Facebook. I'm trying to become a song writer and an actor. A mutual friend of ours knows I recently got in contact with an agency who is considering hiring me for song writing for their music artists. Along with that, I recently was in my first commercial. I'm trying really hard. It's very hard work and I most likely will be signing a $250,000 contract. From time to time I post on my Facebook where I am in life and for my friends to wish me luck. I'm getting closer and closer to my goals, but my ex (who is now married and hasn't contacted me in years) has recently been contacting me a lot all of a sudden. She hasn't said congrats. Just texting me flirty-like convos like she did before we began dating. It almost seems like she's trying to lead me on. What's going on with her?
I took a look just now at singles and dating category. By the questions and answers, it seems as though its populated by kids. That will not be helpful as I'm an adult.
