She's the best. She likes sports. She's hilarious. She can keep up with you on runs (and in the pub afterwards). And you can tell her everything. She's a great friend, who you also happen to want to have sex with.
But does she feel the same way? Sure, she wants to hang out with you all the time and she feels comfortable talking to you about anything, but don't fall victim to misreading her signals as flirtation and end up in an awkward situation. Watch out for these five red flags that you're really just friends.
