My bf lied about graduating college

It has been two months since I got into a relationship with someone I met online. We've been having the greatest time! Meeting each others friends and going out! However, I recently found out that he has been lying to me about graduating college. I knew he wasn't in school at the moment and he said "he planned on going back to university". But, when we were on the topic of school again, he told me the real truth and excused himself for lying. I feel so hurt and don't know what to think. I feel like this is a breach of trust. Better he told me now than later, but I'm doubting his honesty. Who knows if he lied about anything else in our relationship?! He told me he didn't but school is touchy and complicated for him. I don't know what to do. Any advice?
