I'm in love with my straight best friend
Why would you fall for your straight best friend ?
I just think she's cute. Is that so wrong?
It can be difficult for a friendship to survive unrequited feelings. It would be best to try and suppress those feelings unless you think your friend might feel the same.
I don't want to suppress them. I want to be with her and I don't care if she isn't gay.
That could hurt your friendship and she won't remain your friend anymore. You shouldn't impose your sexuality on others. Try to find someone who's gay and interested in you.
