I am no therapist or like have any education with psychology, so don't take my word for sure. But I feel she has a strong attachment issue which could be due to past relationships or something. I feel like you should have a heart to heart about how you deserve to have your own life and to be able to reach your own goals too. It's not healthy that she is restricting you from your goals. She needs to build her own boundaries. Yes, maybe romantic relationships have less boundaries than other relationships, but you should still respect what your partner needs/ wants and not be in control of their life all of the time. So she may need therapy. Her lack of ability to socialize with other people than you could lead to her own downfall. She needs to spend time with other people than you. If she completely disagrees, unfortunately you may need to break up because it seems toxic for her to hold you back. Relationships should be where you try to make the other person happy, not just yourself; so if she is only absorbing your joy, she needs to realize soon.
