Rant about DH

DH and I have a 3 month old and I just found out I was pregnant last week. I am a SAHM and DH works. But he has been on vacation time since before Christmas. Now, I firmly believe in me getting up with LO while he is working. His job is extremely hard and I don't expect him to get up with her at night or real early. Now on the weekends I don't even ask him too, and this whole time he has been off work I haven't asked him too. But this morning LO woke up at 5 and I was just so tired. So I nudged at DH and asked very nicely if he could get up with her so I could sleep just a little bit longer. He said no!! I let DH sleep as long as he can (sometimes 12-14 hrs) and I don't ever say a word about it. And

since we've had LO, I have not slept in at all.

I'm not the type of person to get angry, in fact I have never even raised my voice to DH the whole 3 yrs we've been together. But right now, I just feel pissed and I want to sleep. I'm just asking for one day to get to sleep in. That's it!!
