It's completely your choice and no one should make you feel guilty. But, as other people have said, many of your reasons aren't true, so it's better to be properly informed.
Breastfed babies don't always need feeding more frequently, and certainly not much more frequently. My younger son slept from 12 to 6.30 by 3 weeks and from 9 to 6.30 by 9 weeks, exclusively breastfed.
It doesn't have to be draining. It is physically actually good for the mother as the oxytocin released during breastfeeding helps the uterus contract back into its pre-pregnancy state more quickly. And you can lose loads of weight when breastfeeding which is an added bonus for many people.
It doesn't always hurt. For some people, it never hurts. For some people, it hurts for a few days or a couple of weeks.
You don't have to breastfeed in public and how do you know you don't feel comfortable if you've never done it?
It is true that it can take a long time particularly in the early days but then you are recovering from labour too so it's a chance to rest and cuddle your baby.
Just because the dad doesn't feed the baby doesn't mean they're not involved. They can change the baby, bathe the baby, take the baby out for walks, sing to the baby, carry the baby, settle the baby to sleep at night. You can also express milk for the dad to give or give the occasional bottle of formula alongside breastmilk. But feeding in itself is not essential for a close relationship.
You don't need to measure what the baby is eating because they take as much as they need and then they stop. With a bottle you determine how much you think they should have.
And it's so easy. No bottles, no sterilising, no taking bottles out with you. And it's so cheap. No expensive tins of formula, sterilisers, bottles, teats, carrying cases.
