How do I exit this relationship without burning the bridge?

Long story short, I moved to a new country, got into a relationship with a girl, now I’m moving back.

When we were talking about the future of our relationship I expressed interest in continuing what we have Long Distance.

Now that I’m thinking more clearly, that’s not what I want because I’ll never be comfortable with it or trust her enough. She works in the service industry, there will be a time difference, and investing time in a relationship that doesn’t even qualify as a real relationship doesn’t sound attractive to me.

Now I kind of dug myself in a hole because I expressed interest in possibly continuing what we have. At this point, I want to make it clear that it isn’t what I want anymore. How do I do this without making her hate me and burning the bridge? She is coming to my city in January for work and I want to fuck her again.
