Not sure if I should keep pursuing this relationship or not (19M, 20F)

I’m 19M and she’s 20F. We’ve been talking since April, so about 3–4 months, and in that time we’ve spent a lot of time together, visited each other, gone to a festival together, and talked every day.

She recently told me that she feels like she likes me more than I like her. She also said she’d appreciate more reassurance from me, like showing more interest over text and giving her compliments more often.

The problem is that I honestly don’t know what I want yet. I like her a lot, but I’m not sure I’m ready for a relationship. I just started working full time, I’m trying to get my own life in order, and she’s moving several hours away for university, so we’d be long distance. (6h, she already lives 2h away by car)

I’ve told her I’m willing to try the distance, but I also told her I don’t want to promise something I can’t keep. She said she understands and is willing to give me the time I need.

I’m wondering how people would handle a situation like this. Is it reasonable to take more time to figure out how I feel, or is that unfair to her? At what point do you know whether you should commit or let someone go?
