First wife: I bought the ring after we had been together for about a year and a half.
We went to her moms down in Augusta to visit for the weekend and so I could meet her grandmother who had come down from Illinois for a visit. I had determined that if I got along with her grandmother and they liked ME..I would propose at dinner AFTER asking permission from her mother and grandmother. We all met...everyone loved one another, and her mother and I went to the grocery store prior to dinner, where I saw a little nickel machine with rings. So I bought a fake heart shaped diamond ring (she wanted a heart shaped diamond...so I actually bought a real one, so this fake one was perfect) and presented her the fake one at dinner. Everyone was laughing and she too thought it was a joke and said yes...then Grandma handed me the real one and I did the REAL proposal. Again...she said yes. Seemed sincere. Never heard a doubt afterwards.
Then.....10 years later when she informed me that she was leaving, she told me that had I not "pressured her" in front of her grandmother she never would have said yes
Second wife:
I ordered specialty M&M's (her favorite candy) in pink and red that said "Marry me!" and poured them onto her bed spelling "Marry me" and a heart. Then I ordered rose peddles in pink and red and sprinkled them from the front door to her bed. And I was waiting in the bedroom for her after work.
No pressure...just me this time
We've been married 3 years in May
