Money was a huge drive for her.
Wonder if this is the case for a lot of people suffering BPD.
My ex was the same way. Always money driven. Before we met she had not had one day off for 3 months as she worked 2 jobs. She worked two jobs pretty much the whole time we were together and worked like 60-80 hrs a week.
I think money gave her a sense of security. Unfortunately, I have a low paying job I think that's one of the reasons she left. Onto bigger and better I guess.
