I know that we kinda did have a romantic past and had feelings for each other. But that was September, and we "broke up" stopped seeing each other in November. We were even good friends for about a month.. and even described our relationship as "right love, wrong time".

No guy would want to tell his current friend who he had some romantic past about his new relationship. It would be awkward and can affect present relationship of you with him as a friend because he might think you will feel bad about him being in a relationship or he might also think that it's like cutting you off completely. Anyway you are a nice girl so no guy in his right mind would tell you. There could be more reasons but I can think of only these reasons.
