New boyfriend. Love him. What should I do about this lie?

Ok, I’ve had him 2½ months, am totally in love. Known him a year. Suddenly today he tells me he’s got to go to jail for a couple days. “oh, so sorry I didn’t tell you. I get sentenced tomorrow.” So now I’m mad. Not about the crime, not about the jail, not about the impending probation. About the secrecy. Am I overreacting? He says he was ashamed and scared to tell me.
