i would assume most parents would donate an organ to their children if they needed to and i know full well i wouldnt have to urge my partner to.and if he didnt, which is just not a scenario i can comprehend, then it would be a deal breaker and our relationship would be over quite frankly.
but this isnt a life or death situation or something that both parents can do, its something that generally only a woman can do and she does have bodily integrity and she hast stated she has personal psychological reasons for not wanting to bfeed so her husband should respect that. he may not be happy with it, he may prefer for his baby to have bmilk, if so why doesn the look into alternatives like milk banks and donation, not easy but can be done.
ultimately when it comes to pregnancy and childbirth and bfeeding it IS the womans decision as she is the one that has to do it!
and i am somone who has 5 kids and has bfed for over 9yrs but when with 2 of my children i decided to switch to formula my dp wholeheardely supported me, he made it clear it was my choice and he would support me either way and he is hugely pro bfeeding! but he didnt blackmail me or cajole me he sat and listend to my reasons and was happy to go with what i thought was best.
all the 'give it a go' well yes maybe the op could give it a go, ,maybe she will feel like doing so, but what if she does and then spends those early days dreading every feed, hating every moment of bfeeding and so doing spoils those early few days with her lovely new baby? should she do that just to appease her partner? so that then he can be 'happy' that she gave it a go (tho how you judge what counts as enough as a go..) and then she would not enjoy those first few days and instead of looking back and cherishign those early moments she would look back with sadness at what was an awful and difficult time for her doing something she didnt want to be doing and which she hated.
this is a choice that affects her physically and mentally and yes that trumps the fathers feelings on having the best for his baby. and i wont dispute that biologically bmilk is the best nutrition for a baby, but making a mother bfeed is not good for the mother and i would think in the long run it could lead to huge resentment and maybe even bonding issues, which wouldnt be good for mother or baby.
and as for suggestions that somehow by not bfeeding or co-sleeping she is somehow less of a mother!
and you cant compare nappy changes etc and him refusing to do them as the same thing, they both signed up for parnethood, so they both signed up for nappy changes, bfeeding IS optional given that we live in a society where bottles, clean water and formula is easily available. again a partner that tried to 'teach me a lesson' by not helping with the baby because i want bfeeding would get very short thrift. are there really men that would do that?
she has said that she has discussed it with him and looked at the pros and cons of both, so it hasnt been a fait au complait as you say it has been discussed and looked at, but ultimately it IS her choice and if he is so petty to 'punish' her for not bfeeding then imo he doesnt deserve to be a father anyway.
op i hope you and your partner can move on from this, once baby is here and he gets the opportunity to snuggle up and give baby a bottle, have lovely cuddles etc he will focus on enjoying and loving that baby and supporting you as you become a family.
