I want to stop breastfeeding

Ever since my baby was born he never latched correctly so I stuck to pumping and bottle feeding he is now about to be 6 months and I want to stop pumping it takes up so much time and when I’m out or busy I usually only pump 3 times a day I feel so guilty for wanting to give up and I’m undecided whether I should stop pumping and give him formula or try to teach him how to latch even tho he is 6 months already
