I'm posting like crazy here, but I just have so much going on in my head I have to get it out!

My H just brought D home. He held newborn S for about 15 min's and left. He was rude & angry to me...again. Left w/out saying good-bye and slammed the door. It is so hard to feel this anger directed toward me especially when I am not doing anything to provoke it. I am hurting so badly because of it and I don't know what to do.
One reason he's mad is 'cause I'm not pumping my milk yet (S is only 5 wks old). He wants to be able to take him out...w/out me. He doesn't get that I'm not ready for that...the pumping or being away from him. But he thinks I'm doing it to keep his S from him. That is not why, why does he think I am suddenly that bad of a person? Why can't he for one minute see what I am going thru w/ a newborn?

How do I defend mtself without getting defensive?? How do I deal with his unreasonable anger toward me??
Any help is MUCH appreciated...J~
