It would be more traumatising if they're older. Leave now while baby is still young
Just remember even if you spilt up will need to still see him for her sake. I also agree that it is more damaging in my mind to see parents fight all the time and whatever else. But co parenting should work if you are able to do it the right way and it not be about the parents feelings for one another.
It might be a bit traumatising yeah but growing up with parents that don’t get along would be worse it’s probably better to do it while bubs young so that you guys can figure out your dynamic with co parenting early on
My parents broke up when i was 4/5 years old and I don’t remember a thing about it! Didn’t affect me at all.. I think its more likely to affect a child if they were older and more aware e.g. early teens etc
Children learn a lot about relationships through seeing their parents interact with each other. I personally think it’s more damaging to stay in a bad relationship and them witness that, than to split and them see their dad less often. It’s a really hard situation so I do sympathise.
