I can't do this anymore

I'm not sure if I can handle being with my fiancé anymore ... We just no longer had a baby, who's 3 weeks & he's no help at all seriously! I don't get home he can come home from work and say that he's tired when he comes home to us yet can come home and have energy to go and hang out with his friends all night long. Am I wrong for being this way? Should I tell him how I feel? Yes I do know that taking care of a baby is majority women's work in which many believe but I would enjoy some help & im so tired myself. I stay home and take care of our baby, all day long and night long while he gets a good nights worth of sleep. Yes I know that becoming a mother meant many restless nights but I feel like I have zero support from him at all. Im seriously thinking about handing him back his ring & just leaving with our son because I do it all anyways!
