how to be supportive wife

S

I don't even know where to start this. my hubby and I have 2 kids, a 3 year old and 3 week old. I'm off until August for maternity leave (also I'm a teacher) he recently finally got a different job within his company he's been at for a long time. he's gone like ten plus hours now and when he comes home I feel like I need a break from the kids but with this job, he either does more work or he's too tired to help me. I've been sleeping on the couch with the baby so he can sleep. I don't know how to be supportive of this job. I need advice on how to look at this positively and help him. how am I supposed to feel with no break?
