Friend of a cousin.
Comes from a decent middle-class family.
37. Attractive. Say a 6.
Revealed on second date she was sexually abused as a kid by Uncle.
Doesn't work.
Gets high or drinks every day.
Is seeing a psychiatrist and is on medic
The two questions you need to ask here are:
1. Is she fun?
2. Is she in control?
If she drinks and smokes a lot, that could mean she's fun as hell and likes to party hard or has a really active social life and lots of friends. But that could also mean she's a depressed self-medicating alcoholic. One of those things is fun, the other is not.
As for being in control, If she sees a psychiatrist and takes meds that could mean she's doing all she can to better herself, resolve her issues and move on in life... Or it could mean she's a barely sane nut job who is one day of forgetting her meds away from running into the street naked with paranoid delusions.
Only you will know if you should date her or run, use this as a guide.
