Once,my bisexual friend she had a crush on another friend of hers and she asked me how to figure out if the girl liked her back,since before her friend said she had a crush on someone. I told her to ask her friend to describe who she likes and if the description is like her try going in a little deeper. So,in the end about a week later I'm told my friend now has a girlfriend and so they're dating to this day. I wasn't expecting my advice to work since I know nothing about love.
