MAKE IT A SURPRISE
Even if you've discussed getting married, there is something really romantic about keeping the proposal itself a surprise. Ask her when she will least expect it.
TALK TO HER PARENTS
If tradition is something you are after, talking to her parents before the proposal is a lovely gesture and can provide a good opportunity to involve them in this special time.
HAVE A PLAN
Have a think about where you'd like to do it and what you would like to say, but don't feel like you need to script it. Keep it simple, speak from the heart, and do something that captures the essence of your relationship. Less is more.
You'll only do this once so remember to take a moment, be present and enjoy it. When you feel your heart beating out of your chest, take a breath and embrace it.
AFTER SHE'S SAID YES
All you're probably thinking about is up until the moment she says yes. But what comes next? Prepare a picnic, or organise for friends and family to meet for dinner as a surprise after the big moment. Pop some champagne and celebrate!
