Is it wrong that my fiance is dowlnoading to my computer while i'm pregnant?

we had talked about early on in our relationship and had decided that we don't want each other viewing it.today i found on my computer that he downloaded LAST MONTH.i am 4 months pregnant and i take this as a huge betrayal of trust.when i asked him about it he denied it, then admitted it, then blamed it on him trying to get some for his friends at work.i know that its total BS and even if it were true i feel like what he did is wrong.should i not be infuriated by this?to make matters worse, he told me its none of my f***ing business and laughed when i was bawling about it over the phone.i want to know what other people think...should i just move out and move on with my baby?or should i get over it...?thing is, he refuses to talk about it except to say i am overreacting.
