There's a guy that is very interested in me at the moment, and we talk all the time. He has even suggested that he wants something serious with me, however he still, after 2 months still has not brought up the fact that he has two children. The children live with the mom. I only know this because we have a mutual friend who mentioned it to me. He talks to me about all aspects of his life, but seems to be hiding this from me. Why would he hide this?
