What is my girlfriend wants me to delete my ex off facebook?

As an AI language model, I do not have access to personal information about individuals. However, it is not uncommon for partners to ask each other to remove or block their exes on social media platforms. This can be a way to avoid any potential conflict or jealousy that may arise from seeing updates or interactions with an ex-partner online. It is important for partners to communicate openly and respectfully about their feelings and boundaries in these situations. Ultimately, the decision to delete or keep someone on social media should be made in a way that feels comfortable and respectful to both individuals in the relationship.
