I read your last post as well as this one. I think there is more at play here.
Yes, we moms often bond more or faster with our babies if we have carried them for 9 months, felt every kick and shift, felt every labor pain, and been blessed (and cursed) by surging hormones.
I think the "take a bullet" analogy needs to be set aside. I understand we are in the age of mass shootings and that emotions are raw, but I urge you to stop talking this way because you'll keep saying it to a child who understands your words. Kids do not need to think about bullets. They do not need to know that there may be a choice to save them by dying ourselves. That ruins their sense of security and puts them into a full panic. Please stop.
Now, should your child's father have had the baby on the edge of the bed? No. Should a baby capable of rolling over be in the bed rather than a crib? No. But being an inexperienced caretaker and making a judgment mistake is not the same as not caring or loving. Parenting is not always innate, and there are parenting classes and infant CPR/first aid classes that are very helpful and taught by objective and positive experts. Check with your pediatrician, the children's librarian and your local fire department/paramedics to see what's available. And get a sitter so you both can take it.
But your other post comes into focus - you are having relationship problems. It's not about the baby on the bed, not really. You don't feel he loves and values you, and now you are saying he doesn't love and value the baby. You also make it very clear that this is your baby and that you do not consider him to be an equal parent. You're possessive of the baby. Maybe you don't feel loved and valued by your man - and based on your other post, I can see why. Ask yourself if you are clinging to the baby because you want someone to love you always and forever. If you are giving the baby a "job," to be in charge of your emotional health and security, you're being unfair.
If you feel alone in this, and it's clear that you do, get a counselor. That doesn't mean everything is your fault. It means you need some help in sorting things out, and you need a neutral and experienced person to talk to. Maybe your man is a loser. Maybe he needs help in this relationship. Maybe it's in between. But maybe you need support as well - to feel whole, to feel loved, to accept yourself and not focus on your body changes (last post) and so on. One way we tend to make ourselves feel better is to criticize other people in our lives. Maybe you're doing some of that.
What you're going through is normal. What's not helpful is getting so worked up that you can't think straight and make a better choice about getting help. If your fiancé is such a problem that you want to end it with him, then you need a plan and a vision - and you need someone to help you with that. Your child cannot function and thrive and be loved if one parent is a non-loving irresponsible person who comments on other women's looks and if the other parent is talking about taking bullets but not about taking responsibility for her emotional wellbeing. Taking care of a child means taking care of yourself. Think of the flight attendant safety speech: "Put the oxygen mask on yourself before assisting those around you."
