There's a cute girl I have a bit of a history with who I haven't seen in about a week. Basically, she was in my class before we graduated. I actually hooked up with her (no sex yet) twice a few months apart. First time we were at the same place coincidentally, second time, I asked her to go with me to the bar and we made out and such for a good while with her refusing to come home with me bc "that's what whores do." Anyway, I stopped trying and became preoccupied with other things such as heavy school stuff, family matters, other women, etc. During that time I kind of stopped talking to her. Now it's been like 5 months since I last hooked up with her and I told her (text) that we should hang out some time since we'll be working in the same area. She said, "Yeah definitely!" That was about a week ago.

Anyway my question is, what's a good text opener to get a date with her? Or should I just open with asking her when she's free?
