I assumed nothing; she already mentioned there was no infidelity in the marriage. That alone is the greatest indication that the marriage can be saved.
I do not recall having seen any request to discuss the fine points of Christian doctrine
I have not discussed any fine points of Christian doctrine. I just pointed out a truth.
Can't you see this person is in pain!!
Of course I can. But when a person is sick you give them medicine and hope; not the poison of a false solution. Telling someone a lie that could destroy their future just because you think it will make them feel better is not a sign of Love.
I know you think you are sharing the truth but how can you know what the truth is when you do not know this persons circumstances
What makes you think I don't know this person's circumstances? I know there is no infidelity. I know there are children. Those two signs, by themselves, are sufficient to know that this marriage has love in it, and every effort should be expended to save it because it can be saved. Not "probably can", but definitely can. From her words, I know she is tired, and feels like she's exhausted every avenue to fix the problems. But she hasn't; and it is more important for her to know that than it is for her to hear "feel good" words about the potential for a life after divorce.
