There is a marriage recognised by God and then there is a ceremony that profits some in monetary return and that is coupled with a state tax, all of this accepted as normal. But youngster, if this creep is demanding to try the shoes on before he opens the box, let him take a hike!
The Old testament is a wonderfully educational book that this creep needs to read because had he talked you into sex God would have written it down that he married you, period. and knowing full well how this goes 99 and nine-tenths percent of the time, when he then walked on you because he had, in his dirty little mind, made you a soiled woman and walked away without so much as a divorce decree, that also would be recorded in God's records and the boy would never forget that he had pulled the wool over your eyes and was stupid enough to believe he could do the same to God... it would ruin his eternity because better than 98% of the men in the Church are guilty of this very sin and hate men like myself that are willing to teach this exceptionally unpopular teaching.
If he can not live without sex you can do much better.
