Want to stop breastfeeding

My son is 2 1/2 weeks old and i honestly hate pumping/breastfeeding. Its been a miserable experience and i want to stop.. the only reason i haven’t is b/c its good for him and my SO doesn’t want me to stop till hes at least 2-3 months. I feel selfish for feeling this way but my boobs freaking hurt and i cant get hardly any sleep when it takes almost an hour to pump/feed/change and get him back to sleep in the middle of the night.. any other moms have advice or going through same thing?? Could use some words of encouragement
