1. You need to first start calling a spade a spade, your wife isn't "in a relationship, she's having an AFFAIR.. they are VERY DIFFERENT ANIMALs"

2. Its also your job to protect your wife from the "grass is greener mentality" and momentary infatuations - these aren't MEN she's cheating with, they are PREDATORS.. they are exploiting her emotional vulnerability, it is your responsability to protect her from THEM.

3. Pursue no, PROTEST and EXPOSE -- YES.

4. Educate your wife, get her into family therapy and teach her what marriage means in relation to an affair... and the dangers of infatuations and fantasy... she will just get used and hurt in the long run... my wife got used bigtime.
