What should I do from here? I don't what "activities" are around her area, and going right to her place seems a bit creepy. I really know nothing about women, let alone what would be considered a nice second date for an older woman. She also knows I'm going to back to NYC, though I told her I'd be back in Miami in June, which is true.
I guess I should also say that I'm not really looking for a serious relationship, and I doubt she is with me either, considering the age difference and the huge gap in career progress.
Help me GAF, you're my only hope
So she knows you're 23 and don't live locally? And she wants to see you again? Ignore activities, this is about sex, and both of you know it. Just arrange something near one of your places, and ask her if she wants to go back to your/her place during it.
Ask yourself, what relationship potential is there here? Would you really be out anything if she spurned your advances?
