For some reason I can’t stand my boyfriend anymore

I’m a little under 3 weeks postpartum and I’m starting to feel like maybe I might be starting to exhibit signs of postpartum depression but it’s not really towards my child, I do have some anxiety surrounding him but I still love and feel connected with him but I’m starting to feel very disconnected from my boyfriend, he was so loving and supporting throughout the pregnancy but for some reason when I look

At him now I just can’t even stand him. I enjoy our time apart and i find myself constantly wanting to start arguments and nitpick and honestly be kind of hateful towards him for some reason. He’s done nothing to me but now I just can’t stand the sight of him. Could this be a symptom of postpartum?
