Is my friend too clingy and slightly envious? (Long question but please read it)?

[Dee]

She sounds jealous and competitive to me. The fact you're popular infuriates her, so she's pretending you're her best friend and she is attempting to make herself seem more interesting than she is. Don't overthink it, just ignore it. Tell her you would appreciate her being more honest and truthful with you, than making up a story to prove herself. Tell her if she can't do either or than you can't be her friend anymore. Truthfully, she finds it mandatory to out do everyone, based on nothing but a fantasy and I would tell her to get lost too. It doesn't end in childhood either. I know your kids and it's annoying to you, but grown women act the way your friend does and it gets really bad. Maybe in the long run, you'll be doing her a favor by snapping her out of her delusional thinking now? Good luck
