The main reason why people in love hide serious flaws in their character or harmful dependencies, is because they consider that by manifesting them, they will lose the person with whom they wish to live their whole life; starting from this consideration, when they manage to marry the one they had planned to have a family, the weaknesses and sins preserved in the soul, are expressed little by little and as time goes by in an almost forced way and incited by the differences in personality. The limited physical space of cohabitation, although it should not be so, also has its negative contribution to the problem.

It is when the tender call of God to remember one's own mistakes and clearly manifested in the relationship, is presented to establish a bridge of understanding and forgiveness of the couple. But there are two reasons that could definitely keep the people in question apart: a sentimental attachment of infidelity or irreconcilable spiritual and religious conceptions.

Matthew 18:33-35 NKJV

33 Should you not also have had compassion on your fellow servant, just as I had pity on you?’ 34 And his master was angry, and delivered him to the torturers until he should pay all that was due to him.

35 “So My heavenly Father also will do to you if each of you, from his heart, does not forgive his brother his trespasses.”

1 Corinthians 7:12-16 NKJV

12 But to the rest I, not the Lord, say: If any brother has a wife who does not believe, and she is willing to live with him, let him not divorce her. 13 And a woman who has a husband who does not believe, if he is willing to live with her, let her not divorce him. 14 For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband; otherwise your children would be unclean, but now they are holy. 15 But if the unbeliever departs, let him depart; a brother or a sister is not under bondage in such cases. But God has called us to peace. 16 For how do you know, O wife, whether you will save your husband? Or how do you know, O husband, whether you will save your wife?
