I unintentionally stared at one girl last day. This happened two times more, same person. Also I did the same thing on a friend of her(guy).

She probably thinks I am into her and she is not interested (I actually like her but I already know it's not gonna happen). She also probably told her friends about my actions, they are a group of good friends. I just met them and we had a little nice time weeks ago. After she and her friend(the guy) told them about my inappropriate behavior, they all stopped talking to me. I don't really know why, and I don't want to be seen as needy.

What can I do? Help pls.

(upvote if you ever went through same thing)
