So uh... why am I worried about my brother starting to date someone?

uh... for some reason i feel like when my brother starts to find someone he uh... likes... it feels like he is leaving me behind... i.. dont know why i feel this way... is it because he was always with me instead?
uh... im not the type that would stop him.. Just im worried... i can't shake the feeling that he would feel far away from me...
uh... part two of the question is... am i a bad sister for worrying about this?
