YABU.
You obviously didn't need that extra support. Which is great for you, but some of us would really have benefited from having their partner there.
I won't go into detail to why I needed my partner there. A combination of having a longer stay post birth, a baby with an infection who kept being taken away, a spinal block and EMCS recovery and some of the most piggish, nasty HCP I have ever encountered in my life should be enough for you to realise why I would have loved my partner to stay with me. Rather than me crying as soon as he left and being left unable to move, unable to tend to my baby easily and asking for help and then never seeing anyone again.
If he had been there he could have helped me with everything. He could have stopped that HC assistant who moved my phone from beside my hand on my bed and set it on the furthest away table for no reason. It was my only way to contact any sort of support system at half 11 at night. He could have stopped her from moving my water away from me and out of reach. He could have helped me out of bed, rather than me crying my eyes out pulling the sides of the bed up that a nurse had put down on me, even though it was the only way I could eventually get out of bed.
I can be without my partner, I am not surgically attached to him like some inconsiderate posters think. But that was the hardest 4 nights of my life. Having him there would have helped me enjoy being a new mum. When I think back on it now, I still get upset. It absolutely traumatised me.
But sure, as long as you don't have to be inconvenienced by a man being by someone else's bedside. A man who couldn't give two shits about you or what you're doing. As long as you're fine, fuck anyone who has a hard birth and doesn't get to skip home the next day.
