Well then I guess your standards are higher than God's because Jesus Christ allowed for divorce because of fornication in Matt.19:3-9, why? because fornication divides the one flesh Gen. 2:24, and creates a new union, 1 Cor 6:16. The other case is 1 Cor 7:12-15. While Paul recommends that the deserted spouse remain unmarried in vs 27, he also says that it is not a sin if they remarry (vs 28) and the only condition to the deserted spouse remarrying is that they marry a saved person.
