Guy's Behavior

What should I do? How can I start to talk with him?

I have a crush on someone and i see him rarely and we don't talk now. Two days ago i found his instagram account by stalking and wrote him from a fake account to learn about him but he didn't replied. Then i wrote him from another fake account , he replied this time but he said i dont know who you are, are you the girl who wrote me before and we started to talk but he didn't trust me and suspected about me. We chat for a short time and today we didn't talked. I think he still dont trust my fake acc. The problem is that, i want to talk him by myself not by a fake acc but we dont have any followers in common and if i start to follow him he'll understand that i stalked him and i was that fake girl (he still dont trust) He and his family is our distant relatives. If they werent our relatives i'd write him without hesitation but the fact that they being my relative changes the situation. It would be such a disgrace if he rebuffs me. So I need a valid excuse to starting to talking or following him. Do you have any ideas or suggestions?
