Try to keep this brief.
10 years ago, I started seeing a guy, he admitted he had previously slept with one of my close friends. This friend was and is still in a relationship. At the time, I questioned my friend as to why she hadnt said anything and she flat out denied all knowledge. We moved on.
Time has passed and we are still friends although not as close as we once were. I'm no longer with said ex.
She has 2 children, and frequently posts on social media. We occasionally meet as our youngest DC are a similar age.
As time goes on I cannot shake the idea that her eldest is not her DHs. He is in every way shape and form a spit of my now ex.
6 year ago or so when her eldest was 3.5 years old, I ended up working with her DH for several years and we became good friends too.
Part of me wants to say something to her about her eldest. Part of me thinks I should keep my nose firmly out. He may already know, although to my knowledge he never had an inkling of anything untoward all those years ago.
I just can't shake the fact he may be raising a child that isn't biologically is. But he thinks is. (I doubt it would change how he feels about his son tbh, but surely you'd want to know?!) Argh
