Cluster Feeding

So my son is 1 month old. I believe he is cluster feeding at night and it’s only on the breast. He gets bottles of my milk during the day but at night when we strictly breastfeed, he doesn’t want to come off. But when we do, he stays asleep for like 10 minutes then cries to be put back on. I know he is getting milk it’s like he just wants that comfort of mommy 😔 does anyone have any suggestions because I’m exhausted and he’s literally asleep on my boob right now.
