I think I'm going insane

me and hubby got into an argument...he said I'm over reacting...he told me he is picking up his son (previous relationship) from Washington after the baby is here...I'm having a c section...he said he would leave either before or after the baby is here... I got hurt... he doesn't want me involved with his son and he blames me for him not seeing him

.. he says it's my fault and now he wants to pretty much miss our birth or leave right after so I'll be alone at,the hospital...I'm so upset...I'm can't believe he would even say that..am I over reacting..we live in texas btw..
