Do You Ever Get Over Infidelity?

The reaction to marital infidelity by one's partner has been likened to PTSD after a life threatening event by the American Association of Marriage and Family Therapy (AAMFT).

They have an excellent pamphlet on the topic on their website.

What's your experience? Is it really like that?

If it is, does it follow that getting away from the person who trangressed is the best solution, or you would be better in the long term to work it through and then decide whether to stay or go?
