We never really were "engaged". There was no proposal or specific moment when we got engaged. From the day we first told each other we loved each other, we just always talked about someday getting married. On my 30th birthday, he gave me a diamond and sapphire promise ring to symbolize his commitment to someday marry me, when the timing was right, meaning when he had finished his PhD and gotten a job. After that happened, one day he said, "Okay, we should start planning the wedding."
So, I don't know if I should say we got engaged the first time we talked about marriage, or the day he gave me the promise ring, or the day he told me to book the church for the wedding! If it's the first, then we were engaged for 2 1/2 years. If it's the second, we were engaged for one year and one month. If it's the third, we were engaged for about 6 months. I guess it makes the most sense to say we were engaged for 6 months, since that's how long we had to plan the wedding.
