<human>: I love this girl and she loves me, that's the only reason I'm confused here and would like help.

For the past few weeks, she keeps telling me she wants me to promise her I will take care of her and be with her forever. 

Whenever I mention that I might want to go travelling or study overseas or anything, she gets extremely upset and defensive and makes me feel like a bad person for wanting to leave her. 

She nearly broke up with me the other day, giving me an ultimatum to promise her that  I would do everything in my power to be with her forever or she will find someone who will.

I love her and love spending time with her, but I don't know what i want in the future. I just want to enjoy our relationship. I don't know if I want to travel or live in another country and I can't promise her that I'll be with her forever. 

She can feel that I'm keeping something from her and it's hurting our relationship, but whenever I tell her I don't know what i want in the future she gets really upset and makes me feel like a bad person. 

I feel like I just need to break up with her and move on sometimes, which sucks because i love her 

Am I being unfair?

<bot>: girlfriend wants me to promise I'll be with her forever (commit to her long term), but I don't know what i want in my life and she gets upset and makes me feel bad when I tell her that.
