my bf has a best friend that’s a girl. he says they’re like brother & sister. but they hold hands for photos, she sends him hearts, and calls him love. he says “you don’t know her, that’s how she is.” but it seems weird. i don’t think he’s cheating, but i just don’t trust other girls doing that with him. if they were just texting and hanging out i wouldn’t mind. and even if that is her personality, i would like more girl-to-girl respect from her. should i be upset over the holding hands, hearts, and pet names?
