Offset partied in Miami until 5 AM to celebrate his 32nd birthday without a care in the world -- while his wife, Cardi B, was back at home clearly upset over the state of their marriage.
Offset had not one but two birthday bashes Thursday ... he and his crew were seen inside the Miami Design District hotspot 'Coco Miami' until 3 AM and then hightailed it to South Beach club 'Playa' until 5 AM.
Offset wore shades all night, looking unbothered at both of the parties as he was surrounded by women -- complete with a sprinter van full of 'em.
