No, because Mary's espousal to the Holy Spirit was spiritual; her espousal to Joseph was human. Married Christians are not violating their marital vows when they become metaphorically "married" to Christ (Romans 7:1-6) and spiritually incorporated into the Bride of Christ (Ephesians 5:25-27, Revelation 19:7, 21:2f), either.
Um, duplicity doesn’t bode well for your reasoning abilities. According to the BIBLE Mary was betrothed to Joseph thus vowed to be his, THEN the Angel appeared to her and she consented to surrogacy of ‘the holy thing’. Gestating a child is a physical behavior. BUT, consenting to surrogacy does not take from Mary a sex cell pledged to Joseph. Catholiciism insists that God took a sex cell from mary to make Jesus’s body and behavior mechanism. Is the god of catholiciism a defrauder, of Joseph? Try to straighten this Gordian catholic knot, without contradicting The Bible.
