Hi Airborne
I think she might have gotten lonely or maybe she's having problems on the dating side and is looking for some male companionship. It looks like she might be missing you and that's always a fair ego boost
Hey, you know what i always wanted to do, but never did for some reason. When an ex (Who dumped me) asks me to go out with her, to actually DO go out with her and act so cool and friendly and flirty (like you do when you're out with a hot date) at the same time that she would badly want me back and then when she thinks she has me wrapped around her finger tell her sorry, "Not yours anymore" and simply walk away like i couldnt care less about her - because i couldnt care less for someone who dumped me to begin with. I reckon that would be such a bummer and would kinda let the ex know exactly what it feels like to be on the recieving end...
Good luck!!!
