Backstory I fucked up by dating a girl who works for the same company, luckily not the same department, but nonetheless foolish on my part.

After we had been dating for a few months I took a temporary position in another city, which made her break up with me, but then wanted to make it work right before I left and I gave in because. . .I'm an idiot I guess.

We have been doing the long distance thing without too much trouble except all the time spent travelling. However, I was recently offered a better position in a totally different location and wasn't planning on telling her until it was time to go back because I didn't want her showing up where I work and causing a scene in front of my co-workers. But since we work for the same company she found out while she was visiting me and spent a whole night dealing with the crying and manipulations until she could go back home. A lot of things came to light that make me want to be in relationship even less than I already did. Since it wasn't possible for her to head back home until the next day I just took it and played the I'm sorry card and agreed to figure out going back to my original position instead of taking a new one.

I don't want to continue the relationship nor do I want to give up the new opportunity, but I've just been trying to delay telling her for sure until I can get my car out of her garage and because if I do tell her she will show up here in person demanding to do the break up in person.

She has been incessant in asking me if I've found out any news about being able to take back my old position and if I still want to do what she wants basically.

I don't want the same things she wants and don't want to be tied down to a committed relationship or get married or go down any similar road.

I've really regressed in living an unplugged life and resented myself along the way, but am happy that I'm getting out of this relationship one way or another.

I need help and/or advice on what to do and what to say to get out of this without having any blowback at work.

Many thanks in advance for any advice!
