Fiance postponed wedding

We've been together two years and engaged 3 months. When I started planning weddimg just a week ago he was fine. Then one night he tells me he wants to wait a year or so til we get our finances right. Well of course my heart is shattered. I umderstand his reasons but this is a sudden change from before. So my question is, is he getting cold feet and should I assume its permanently postponed? That's certainly how I feel right now.

Thank you. I know I should talk to him about it. Just been afraid to.
