Well I guess my concern is that mom is having this relationship with a married guy and my kids know about it. Doesn't this impact the child's proper development concerning relationships. Mom, has also not been 100% honest with the child in that she has downplayed the seriousness of the relationship. In addition she has been caught by the kids telling little lies about what she is doing when in fact she is with the boyfriend. It just seems to have created distrust between the oldest son and Mom.
