I don't think it is that odd to come to LR for advice, you tend to get some good information from both sides of the coin, albeit a bit too "tough lovey" at times.
I agree with "not FP," I think she is confused about what she wants to do and sees this as a way to do something cool with her life while she still has a chance.
If she has always dreamed of doing this, that is one thing. If it kind of came out of nowhere, it is likely due to her not knowing what she wants to do with herself.
I had a stretch of about 3 years where I was confused about my career. I had a long time girlfriend (now she is my wife) and we wanted to get married, but I did not have a career. I was working as a loan officer in a bank and hated it. I was training my butt off, but that is not related so I digress...
I looked into going overseas to teach English, but realized that it would likely mean the end of the relationship. Instead, I went to see a career councilor and it actually helped me figure out what I wanted to do. I went into thinking it was stupid, but it helped.
I had to move to another State, but the job was great, the city was awesome and I proposed to my girlfriend. She happily accepted, we moved and everything worked out. I am still in the same field, but own my own company. We are happily married with kids (I am a year younger than you).
It was easier for me b/c my wife wasn't a driven career woman. Her passion is art (and now being a mom), so she could do that anywhere. Her only requests are that we live somehwere with a good yoga community and cool restaurants, so she is happy in most progressive towns. Now we are settled, obviously, but i am so glad I did not make that decision.
Like I said earlier, if this is a passion of hers, let her go. I just found that with me, it was just something cool to do since I was worthless at the time.
Is this woman a career woman? Would she be unhappy if you proposed and she didn't have her own "career?"
