So I just was at an event and ran into my friend's ex-boyfriend and his wife. My friend is doing OK now but was not OK for several years after their break-up. Even though her ex met his now wife after breaking up with my friend it was still hard for her to see their relationship unfold. So...he genuinely was interested to know how my friend was doing. He asked me to tell her hello from him, and it was heartfelt. Do I do it, or ignore it?
