Is only the one who cheated to blame?

Yes, it was he who made the choice to break the trust. No one forced him to betray, and there is always an alternative: to talk, to honestly admit the problems, to leave the relationship. From this point of view, the guilt is obvious.

But what is behind the betrayal?

Rarely does betrayal arise "out of nowhere". More often it is the result of:

lack of attention and warmth,

lack of respect and support,

unfulfilled needs (emotional or physical),

accumulated grievances and silence.

When one in a couple feels undervalued, unloved or "unnecessary" for a long time, this opens the door to temptation.

Shared responsibility

Cheating is a symptom. Yes, the cheater bears the main responsibility, but we should not forget that the relationship is built by two. If there was no trust, closeness and dialogue between them, then this is a common failure.

And what next?

Here it all depends on the couple. Some consider cheating a point of no return. For others, it is a chance to reconsider the relationship, build new boundaries, learn to hear each other.

The main question to ask yourself after betrayal: "Do we want to be together anymore?" If yes, both will have to work, sincerely and without self-deception.

👉 So who is to blame?
The one who cheated is to blame. But the responsibility for why it came to this is almost always shared.
