Dear Emma
Getting married abroad may seem cheaper, but it will be more expensive for your guests and will probably limit those who can come.
As to the cost of getting married in this country, then there are certain costs which can't be changed, such as the charge made by the church or register office. Why not consider what your priorities are. Perhaps list the things that are most important, eg having all your friends and family there, the number of bridesmaids, making your vows to each other, the honeymoon, buffet or sit down meal etc. Then decide on your budget and work out where you can cut corners.
One thing to remember is that your wedding day is simply that - one day in your life. You will only remember some of it and it won't really make a huge difference to your married life together. For me after over 25 years it is the ceremony and the promises that we made that I remember most rather than the reception or even who was there or what the dress was like. If you can keep things in perspective that this as about your future life together rather than a big occasion that will fade in your memory, then you may well be able to have a wonderful day within your budget.
Why not also include some
marriage preparation in that budget, investing in your future together.
There is a really good book
here that not only looks at how to plan a wedding but also looks at your relationship too. Why not consider getting hold of a copy.
All the best
Kate
