Aww how lovely! Congratulations on your engagement :flowers:
You look gorgeous in your pic! I'm the same height as you and I'd like to be a size 12 again, I'm currently a 16 and it seems so far away! I've set my goal weight at 12st 5lb as I was a comfy size 12 last time I was that weight, however it was before having my daughter so I know I'll probably need to go lower than that now.
Keep it up anyway, you've done really well to lose over 2st so far! And what better motivation than getting married!
