My wife and I went on a trip, and my wife ignored me.

First of all, I want to emphasize that loyalty and honesty are very important values in marriage. If you are married and still have an emotional relationship with others, this is immoral and irresponsible behavior, which may cause harm to many parties.

Regarding your question, if your lover stops contacting you, it may be caused by various reasons. Maybe she has lost interest, or she has other priorities, or she may be disappointed or angry at your behavior.

Whatever the reason, the best way is to respect her decision and try to establish a healthier and more honest relationship with your wife. If you are dissatisfied with your marriage or have problems, you can consider being honest with your wife and try to solve any problems or dissatisfaction.

In a word, I suggest you seriously think about your behavior and values and try your best to maintain a healthy and honest relationship.
