Hi, I can understand your concerns and I would suggest you to speak to your partner about these concerns as well. It will be helpful for you hear her opinion as well. You are very young and can still shape your career and ambition in a way to meet her family's expectations provided you want to do that. A relationship will work out if both the partners accept each other for who they are and align their choices in a way to be with each other. This balance is dependent on both the partners. Not only on one.
Next Steps
Speak to your partner and have an open discussion about your concerns.
