The co-sleeping thing interests me as I'm 29 and co-slept with my Mum for a really long time (on and off till I was 8). My dad used to sleep in my single bed, so a similar situ. My parents are still together but have a totally platonic relationship now, and sleep in different rooms. I was an anxious kid, but I think my Mum didn't encourage me to stop sleeping in with her because of the problems in their marriage. As an adult though, I feel a lot of guilt about the fact that as a kid I relegated my dad to the small single bed. And I feel bad that I was a reason my parents (specifically my mum) used not to deal with the problems in the marriage. Idk but looking at the situ, from someone who grew up in a similar one, it isn't healthy for anyone. They need to address what is happening with Ethan that means he needs to co-sleep, and what is happening in their marriage that means Stephen is in the single bed!!! All a bit fucked up. And I know cos I lived it. Final thought: I feel shame about the impact my co-sleeping had on my parents' marriage, and no-one knows but my immediate family. I feel bad for Ethan with it being all over the internet.
