Thank you for the advice, Satil. My boyfriend is very well off, as are my parents (who already agreed to pay for half of the wedding, up to $50,000), but we are not being cheap. It wasn't so much that we wanted an expensive wedding, but what we wanted was a bit... expensive. It's my dream to be married in Alnwick Castle (where they shot the Harry Potter films; 1, 2, and 6 to be specific), and by the gods I will have it. Everything else is inconsequential.
As I said, however, we are looking at a wedding seven years in the future, at least. Plenty of time for us to break up without a penny spent. But I feel like we have a bond. Maybe it will not be romantic in the future, but it will always be there. If I marry another man (or woman), I know he'll be one of my bridesmaids (I've already got one man on that list, so why not?) and I hope he is always a part of my life. We really support each other. We help one another through hard times, through difficult emotions, and through the simple things and there is something really strong in our relationship that I've always valued, even before we began dating. Oddly enough, we have discussions about what we'd do if we did break up... and we both decided that we'd still want to have a child together. I know that seems odd, and a bit pre-planned, but we both have very specific ideals about child rearing and we have what the other lacks. That, and the financial stability of it is perfect for us. Besides, after all these years of dating, at least the sex wouldn't be as awkward.
