<human>: So this weekend I told my girlfriend that when I traveled at the end of next year I wasn't sure whether I wanted to be in a relationship. I didn't want to lead her on and go overseas and then find it too hard and dump her as I don't think that's fair. I also don't want to waste her time for a year. I've always wanted to go travelling and I've always seen it as an opportunity to experience the world. I don't want to have any regrets of my trip and feel like worrying about a girlfriend back home and what I can and can't do would be difficult. 

The problem is I feel like a complete prick. I've broken her heart and I don't know how to make her feel better. I personally don't want to break up with her now as I have a blast with her and really enjoy spending time together. Ideally I'd like to enjoy the next year together, part ways and then see what happens after. I completely understand if this isn't what she wants and I've told her as much. I'm second guessing whether I should have told her or whether we should just break up or whether I'm absolute jackass for doing this in the first place and whether I should just try staying together when I leave. I guess my question is how do I approach this?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Told my gf I wasn't sure if I wanted to be in relationship when I traveled. Not sure where to go from here.
