DC who is 9 with ex, live close by in same town. Ex has a wife who works with one of my friends in said town. He's been with her for around 7 years now married about 2. We all get on fine. They also have two young DC.
My friend and exs wife work on different teams but within the same small building. They don't talk loads but are friendly enough and sit by each other. Exes wife sits next to another colleague who she's apparently very close to.
Basically my friend overheard her talking with this friend/colleague about my child, saying she can't wait for him to go home i.e. back to me on Sunday (week on week off) and since having her children she doesn't 'have the patience' anymore. Apparently this came about because exes wife's friend has started seeing someone with children and exes wife was 'warning her off becoming a step parent'.
I realise this is 3rd party info but I don't think my friend would lie to me about what she overheard.
Should I say something to my ex? I'm aware I don't have the full picture so I wasn't planning on going all guns blazing or anything. I feel very awkward now. There have been issues since their young DC were born where our son doesn't feel like his dad prioritises him sometimes but he still enjoys going and loves his dad and his siblings.
