Re: Being friends with your Ex
Of course letting his wife know about what’s going might break up the marriage. Clearly his moral compass is so low that he’s not willing to be faithful to his wife. And so far, you also have not cut off all contact with him even after after finding out that he has feelings for you (and you still love him).
So if you can’t muster up the courage/strength to cut off contact with him, and will continue to answer his phone calls/meet up with him in person…then yes, you should let his wife knows what’s going on. So that innocent woman can at least decide for herself whether or not she wants to be a part of this.
