<human>: Can you condense the text into a few key points?

I'll cut to the chase: been with "Sally" for three years. We are planning on marriage, but want to get married debt free - hopefully we'll be done paying down student loans by 2017. We live together, it's been fantastic, no complaints, etc.

Sally is a dentist, and lately she has been suggesting that I switch to her practice. I have no desire to switch dentists. I've been going to the same dentist for nearly 10 years and I like my dentist. Her practice isn't struggling or anything, but I think it's bizarre to have  my girlfriend and future wife be my dentist. She keeps bringing up how her practice is in my insurance network, etc., but I just don't want to do it! I am sure she is a fantastic dentist, but I don't want her to be mine. She gets sad about it but like...I just don't want a family member to be a healthcare provider. Help?
<bot>: My dentist girlfriend wants to be my dentist. I don't want to switch dentists and I don't want her to be my dentist. What do I do?
