There are too many secrets in your relationship. If he is keeping secrets from other important people in his life, how can you trust him not to keep secrets from you? I don't think what you feel is love. It is either lust or infatuation. If you enjoy his company, you can probably continue to enjoy that, but if you are thinking about a long-term relationship and possibly starting a family, I think you are opening yourself up to a lifetime of drama and unhappiness. Good luck.
