Reason to quit

Da

Sorry I didn’t know where else to post this.

I started working at a law firm a couple of months ago. I love it there BUT it’s only part time. When they offered me the job I said part time is ok because it was better than nothing and I needed the money.

Now my fiancé’s company is hiring for a full time position and they offered it to me. It’s a lot more money because it’s double the hours.

We are trying to move across the country in a few months so we really need to make as much money as possible.

The law firm was never meant to be a long term thing anyway (because of the upcoming move) but of course they don’t know that.

I will have to quit on short notice and I feel like such an asshole. If I tell them the truth, that part time is not enough and I lied and I really want full time, I’ll feel even worse.

Is there anything I could tell them why I have to quit suddenly without looking like a complete jerk? They’re super nice people and I would have liked to use them as a reference in the future.
