As for the person you are talking about, he is probably not your twin flame if you don't think he is. It's all about how you feel you know, and you're basically the only person who can tell if he is or if hes not.
But he might be an important person in your journey since there are so many similarities, so I suggest you keep in contact with him and see what happens, you never know. * I've even heard of individuals who found their TF's through people which they had a lot of similarities with concerning the 11:11 phenomenon *
