<prompt> Human: EDIT ITS MY GIRLFRIEND - NOT MY SPOUSEGreetings,I recently got a significant raise at work and will be making 88K at work overtime rate nurse and am expecting to make 90-100K on average for the next year. Prior to this, I was making 55-60K rate and girlfriend is making 30k graduate lab student. Long story short, I was making 2x as much and am now 3x as much as she currently is. She and I sat down and I voiced my opinion that I felt splitting bills 5050 as we had done previously was no longer fair due to the differences in income. We live frugally and responsibly and had leftover money each month, so general expenses were usually not an issue.Can anyone offer their advice on how to now handle expenses when our salaries are very different?  <response>: Marry her and you will pay 100.On a serious note - this is not a PF question. Its a relationship question. From purely financial standpoint its best to minimize all of your expenses.
