I used to have a crush on my brother.
Has that caused you problems?
I felt like I couldn't trust him with my secrets, and I was embarrassed around him.
Your 'crush' are probably just other feelings. Like admiration or respect. Analyze your thoughts and feelings.
More than likely yeah. I think I realized that and got over it.
It's good that you realized that. Otherwise, it could have been really awkward going forward. It was good that you took the time to process things and realize what you were really feeling.
