The name here is not relevant. Was there anybody at all who maybe teased you about having a crush on her? Anybody who thought your friendship was a bit too close? A family member (dad, siblings, cousins) or classmates or friends?
And why did you hate her boyfriend? Did you hate him because he was a jerk and didn’t respect her or hurt her? OR…did you hate him because you didn’t want her to be with any guy? Because, keep in mind, that she didn’t like you hanging out with any girl. SO, if you also didn’t like her hanging out with any guy…then your similar actions could possibly mean mutual interest.
