I am more familiar with the roles reversed. I know of a few cases in which a wife discovered the husband was cheating.

None of the women, naturally enough, simply shrugged it off.
In one case, the marriage ended in divorce.
In two other cases, after a long period in which the husband went to counselling, the couple went to counselling, the husband participated in an ongoing recovery program for sex addiction, AND the wife saw changes in the husband's behavior in other areas of the marriage, especially regarding how he treated her and reacted to her concerns, the wife eventually could forgive, because she had confidence that the husband had changed and was consciously working a lifetime effort of improving himself spiritually and emotionally.

I would not consider such a wife to be weak. I would call her courageous and strong.

If you reverse the genders in the above, I would come to the same conclusion.

No.

Infidelity is only a symptom of a deeper issue, and it typically involves both parties. In not one other area of life to we excise people for one mistake; why end all the minor and major successes of a relationship for one infraction? Relationships take work and anyone not willing to honor that shouldn't take one on.

No, I think that's his choice. It wouldn't be weak to forgive, forgiveness is never weak it's one of the hardest things to do.

No…. If he did it only once and out of love…

Depends on the situation. Forgiveness requires repentance. That’s a biblical standard. If she (he in vice versa truly repents and is actively making amends), the they are not weak per se. It can be justified. But it’s very situationally dependent.

It is not weakness but the root cause must be ascertained. The problem must be remedied and if no remedy exist then the relationship should end.

No, I would not judge him that way people can recover from infidelity it takes a lot of work and both partners realizing it can't happen again.

it really depends on the circumstance, and how often. I would think he was strong if they could work it out amicably.

Forgiveness is not weakness, but that relationship is doomed, and he needs to get out.

Not if she properly humbled herself before him and accepted cheerfully his chastisement!

Forgiveness isn't weakness; but bitterness might be.

I dunno I think it would depend on who it was with

not weak, but i wouldn't take them back. 😇

No i wouldn't. Would you?

No, maybe strong.

no...it requires strength

Man or Woman its wrong.If you fancy another person break up first at least.

Yes.

No

No

I don't think I would say "weak." Has she apologized and is she genuinely repentant? Or is it clear that she doesn't care about his feelings and will do it again? If the latter, I might consider him foolish, but I don't think wanting to hold onto a relationship with someone you love makes one weak.

No, but if it were to happen again I would suggest seriously leaving her then.
Once can be a moment of weakness, but the second time is sign of bad habits developing.

Thats why Open Marriages both Adults Agree sleeping with other people

Yes, he is weak, I forgave her and then she continued without my knowledge. The forgiveness was a waste of time

if they are in a Polyamorous relationship then no, if we are talking being unfaithful, i think he is Nieve, as if it happens once then it will happen again... like i knew with my ex i got her from her being unfaithful with me, and so when she fucked her ex i wasnt surprised, i wanted to forgive her as she claimed to be drunk, but i also accepted that it was very probably over.

yes. I kicked mine out. hardest thing ever but I did it because she a hoe

well depends. Yes if he forgives, no, he is stupid if he goes back. Whatever was wrong in the relationship will continue to happen and infidelity will continue

Not weak. Just dumb.

No just dumb

I wouldn't think him weak, but I'd think he's being stupid.

Almost always yes, if he hasn't cheated on her.
