Should i breastfeed 2nd baby boy

So with my first i breastfed full time for about 6wks then on and off for a few more weeks using a bottle w/ formula more and more because it just got to a point where my back was in excruciating pain all the time and even after i stopped it still took a few months for my boobs to go back to their normal size and i already am a 34GG so they were soooo big and always leaking and right now i already have colostrum but i cant decide if i should breastfeed or not i mean i did enjoy it but the back pain was horrible not sure if it was from boobs or what and i just felt really uncomfortable with dh touching my boobs at all and i used to have feeling in them and now if he touches them or anything theyre just numb and i was kinda starting to get feeling back before i got pregnant again (25w w/ 2nd boy 1st one is 13m) also i felt pressured from dh and mother in law to stop b/c they thought my milk was causing ds to be colicky which was so stupid but i was always getting bitched at and we lived with in laws at the time (we will have our own place now and be alone) and i was tired of hearing shit from mainly her and whenever she had ds she would give him bottles when she thought i wasnt near and i remember being so pissed and then having to go back to work cus we needed more money too and it was just a very stressful time and experience and i dont know what to do with next baby....
