Do I quit breastfeeding?????

I don't want to quit breast feeding. I supplement at night only once because one bottle at night and he sleeps through. He's 6 weeks today. Well anytime I breastfeed he's never satisfied. I breastfed for an hour this morning and when I took him off because he refused to wake up after an hour my breast were still leaking from how full they were for some reason. Well he woke up and showing signs of hunger and crying so I keep feeding and keep feeding and he never stops. But if I give him a bottle he is happy and falls asleep for a few hours then wakes up and hangs out awake with us then he shows hunger again. What do I do ?
