I've never posted anything personal before so here goes. My oldest is fathered by someone I dated for many years but never married. We split unamicably at first but have worked really hard to not just be amicable but to be friends as well. Well, it's gone pretty well until recently. Our son has called 3 times out of the last 2 months he's been over there (he goes every other weekend) complaining of stomach pain. He really did throw up the first time but the other two times have been in my opinion, feigned illness. His father has a new baby in the house and I believe his lack of sleep and patience is starting to affect his interaction with our son while he's over there. He was extremely rude to me on the phone and suggested that our son was faking just so he could go home. I'm at a crossroads of not knowing whether or not to divulge that I do indeed think he is faking because his Dad is not being so nice and keeping it to myself because I know it will hurt his father's feelings ( my son's concern, not mine) and that it's probably something that will pass when the baby gets older and his father is getting more sleep. On the other hand, I feel keeping that information to myself will only further hinder how my son is treated and I need to be the backbone for him since he is a child. What would you all do?
