Burning bridges

So yesterday I found out my husband was lying to me about financials. He took money out of a savings account that we have and hid it from me. He made two transactions, one that we needed for our trip, and another one for himself doing what he pleased. 
This was over a month ago and he never told me. I only found out because I called the bank to check the balance to keep our books right. 
When I confronted him, he said he was sorry and he felt terrible for keeping it from me... But how bad could he have felt. He still hid it from me. 
This is the third time now that he's lied to me about money. I want to trust him again but I don't know if I can knowing he keeps burning his bridges.
I don't know what to do 
Anyone have any advice?
