Ex-Girlfriend (16F) left me for a mutual friend (16M). She’s been staring at me whenever she see’s me talking to another girl and it’s weirding me out. She sent me a text asking why another girl was at my house.

She’s young, stupid and immature. Ignore her jealous bullshit and move on

Block her and ignore her. She may have “moved on” but she doesn’t want you to move on.

Do your best to utterly ignore her staring. Act like she doesn’t exist.

As for her texts, just ignore them. Also probably best if you just block her number. It’s none if her business and engaging with her like this will on enable further innapropriate behavior or her front.
