What would a Christian betrothal look like?

Our Messiah is betrothed to us. "and I will betroth thee unto me for ever; yea, I will betroth thee unto me in righteousness, and in judgment, and in lovingkindness, and in mercies." - Hosea 2:19 "For I am jealous over you with godly jealousy: for I have espoused you to one husband, that I may present you as a chaste virgin to Christ." - 2 Cor 11:2 So, how does a Christian get betrothed?
