Religiously speaking, that's what a marriage is in my world - the union of two souls. Obviously there are other parts to it legally and practically that don't apply if one of you is dead, but the religious part is usually the most important to people.

'To love you with all my heart, to share with you all my soul' - straight from my wedding vows.

...So yes. That is what I'm getting from it. By my own standards, you're engaged.
