Love could really hurt me here, so please advise me as best you can?

To make a long story short, I met this guy in an interest group and we clicked so much..we chatted for 6 weeks, exchanged photos, called by cam and decided to meet. So we did 2 days ago. got on well, kissed on the cheeks good night and he told me we'd chat. Today he contacted me & said 'you don't feel comfortable with me do you?', I said , 'I told you I am very shy'. He said, 'I thought you were not interested so I closed up myself'. I said 'you are so wrong, you have to give me a chance, if you want'. He said 'I have to be honest, I met someone recently, we've met twice, but it is not serious and I don't know if it will be'. I said, right, clean out yourself and then we can meet. He told me that he thinks I'm a very nice person, interesting and hot. I told him 'I'm monogamous'. He said can we talk about this tomorrow. What will I do? I really like this guy.
