Ummm im going out on a limb but alter ego might be worth a shot (4 months off 22 myself). It gets good responses just dont OD to much if you are after good results consistently.
Jambats mix could work well.
TE - You could try the scentless version
SOE - This could be useful for softening her up for starters and getting close again.
If all else fails and the stuff does work but she either hooks up with someone else (trust me this happens a lot - friends on the edge of our social circle hook up etc)
or she aint interested but you get responses elsewhere use this stuff to go find someone else give them some attention but if they look like dragging you along follow JAMBATS advice and mine and move on quickly.
