Attachment to partner

Someone please tell me they’ve experienced the same after birth/postpartum. I feel SO attached to my boyfriend since returning home from the hospital with baby. He has taken 2 weeks off with us due to being self-employed so is returning next Monday and I’m absolutely dreading it. Not even because I feel I can’t cope on my own I just hate the thought of him not being here 24/7 with us. I cry quite often at the thought of him not being home. Is this normal?
