My boyfriend and I are pretty straight forward with what we want/looking forward to in the future. We dated for 2 1/2 years and recently spoke about getting married at a court house since we're already living together. We go 50 % on everything financially. I must say I'm pretty much happy with him and the accomplishments we've made as a whole. But recently he's been hinting about what my preferences are in the engagement ring I want and sort of trying to convince me of choosing a cubic zirconia vs a diamond because someone he knows suggested it. Am I wrong for wanting a diamond, which he makes more than enough currently to afford one. Please advise
