Hi Lost there are always two sides to a coin or a LBS & WAW.
Actions of others can precede one's feelings, especially when those who are cared about & trusted, take actions perceived as thoughtless, disrepectful, and controlling. One partner's actions affects the other.
The thoughts that arise because of those feelings & the actions one takes to act on those thoughts are one's choices and one needs to assume responsibility for them.
Accepting responsibility for those choices, does not negate the actions of the others however, that started the process towards that choice. If they choose not to take responsibility for their action & role in affecting their partner, that is their choice, their partner can not 'make them'.
Both partners make choices in the marriage. An affair is a symptom, of problems in a M, not the thing that causes the problem. It does create other problems, though.
How are things with you today? Peace Bridge

Taking the road less traveled because those encountered on the way may be just as unique.
