It's me.. who said forgive in the other thread.
Forgiveness in a marriage, on which years was spent is essential to keep a marriage alive. It is not necessary that you have to go through abuse, etc etc...take time alone, go for counseling, give it a good try, before you call it quits
This is what was read at our wedding - from 1 Corinthians:
4 Love is patient, love is kind. It does not envy, it does not boast, it is not proud. 5 It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. 6 Love does not delight in evil but rejoices with the truth. 7 It always protects, always trusts, always hopes, always perseveres.
8 Love never fails.
Love is all of the things above. But so is trust and honoring the other person and their feelings and rights. They have the right, not to be cheated on. They have the right to have a spouse or partner that they can depend on and lean on when they need to. Any kind of relationship takes work from both parties. And sometimes you can just forgivesomeone so many times, before you realize that the other person is not trying to make the marriage/relationship work. And probably in that case, the other person (that didn't try) really didn't love the other person like they should have.
