Well, I still don't know what she means. So, why would you feel bad for my brother's GF? She's an adult. She's been dating him for a few years. She's aware of what's going on, etc. She doesn't make as much $$$ as him, so parhaps she's just using him to get her credit back on track and all of that? Maybe we should feel sorry for him for having a GF that's just using him to get back on her feet?
I guess I don't have much pity for people who KNOW what they are getting themselves into, and have the ability and the choices to say NO. She knows how he gets treated by the family, she knows that they are making these financial choices together, etc. It would be like me complaining about some of my husband's past choices; I have known about them all along, and married him anyways, so don't feel sorry for me. I am in my own bed because I made it that way.
I also told her to not wait around and put her life on hold for someone who might or might not want to marry her someday. She has a "timeline" of when she'd like things to happen for her; kids, etc...and if he doesn't fit that timeline, then she shouldn't wait around.
