Communication and trust.

My boyfriend(22) and I (20) have been together for almost 2 years. The other night we were laying in bed just talking and he rolls over and tells me he has popped holes in a couple of the condoms we used. Thank God I wasn't ovulating at the time of sex. But I'm not ready for a baby but he is. He told me because he felt guilty and realized how immature it was. I'm mad but he came clean about it. How do I trust him now? Ladies help.
