Well...
I met Mrs Knox during the last week of January 1998. On Valentine's Day, two weeks later, I gave her a dozen deep red roses, an indication of my feelings for her, which couldn't possibly be more serious. By this time, anyway, we had told each other how we felt. Nevertheless, for the first year and a half, we dated, although we saw each other every day, and I spent more time at her house than my own.
I moved in with her in the summer of 1999, after she had lost her job, and she needed help with the bills. Me and her and the cats in a 600 square foot condo consisting of one bedroom, one bathroom, a kitchen the size of my shoe, all together. Here, I thought, was the true test. Could we live together, in the same place, even though we'd been joined at the hip since that very first date back in January '98? It worked out well.
I proposed, out of the clear blue sky, on Mother's Day, 2000. We were at my parents' house for dinner, and when we left, I started singing a song, to myself, in which there was a sort of innocent marriage query...nothing really proferred, nothing serious. She then grabbed me, embraced me, screamed "yes", and kissed me. I said, "I hadn't really meant it in that way, but, WILL you marry me?" I will never forget the look of joy in her eyes when she voiced her assent. Something that will last a lifetime. We then went back in and told my parents, and they were overjoyed as well.
The point, Jester, is that we took the time to get to know each other as well as could humanly be accomplished. Two and a half years before the marriage proposal. We cemented our relationship, and created our world, long before I proposed. In fact, it was exactly a year until we got married.
There's no hurry...weddings are a lot of money, and if Smurf is like any other girl (I'm pretty sure she is), she had her own ideas on the wedding and what it's all about for quite some time. Defer to her on this! You'll be very happy you did. Take some time with the planning, and enjoy yourselves. In the meantime, grow your relationship. It's most important.
Good luck.
