How to balance a long term relationship and travel

Hi everyone,

So I've been struggling today thinking about the future. I've always wanted to see the world (preferably with a partner) I've even wanted to live abroad. However I (27 F) also want to be in a long term relationship and have a family. In a perfect world I'd meet my partner and travel together and have a child and live abroad or back in the US. However whenever I meet people who want long term relationships they usually are against traveling or scared of going places outside America. I guess my question is has anyone been able to balance a long term relationship with seeing the world? Where are you able to meet your partner?
