Any time a chick wants to take a pic with you on a date, it's an extremely good sign. I've never once had that happen where the situation ended badly (unless it was my fault). Congrats, breh.
Only advice I would give is dont put all your eggs in one basket.
A woman can seemingly be head over heels for you one week and ignoring calls/texts the next. Treat her as the no # 1 prospect and prioritize her over women that dont reciprocate your interest as much as she does, but do not stop dating until both of you have verbally committed to being exclusive. I would also advice that you allow her to be the one to broach the topic of exclusivity. Until this happens, DO NOT stop dating (and fukking) other women.
Congrats again, breh, very happy to hear
