I need help

Is it too much to ask to have a little help with the baby when he gets home from work? The baby is 3 weeks old and doesn't sleep more than 2 hours at a time and wakes up whenever you put him down, so I'm literally only getting maybe an hour of sleep at a time. I'm surviving on 3 non-consecutive hours of sleep, while he gets 6-8 hours of undisturbed sleep every night because he works. The baby is having trouble latching so I'm also having to bottle feed him and pump, which is time consuming. Today my SO came home, showered, and got a snack before even checking on me and the baby. I asked if he could please take the baby once he finished eating so I could pump because my boobs were hurting. Well he didn't. I came back in the living room to find him with feet propped up watching tv. I am exhausted, I barely have time to take care of myself during the day, yet he can't help me out for a couple hours in the evening.... I'm so frustrated
