It depends on the situation and your intentions. If you are looking for closure, you can send a message asking why they ghosted you and expressing how it made you feel. However, if you want to move on, it may be best to avoid contacting them again. It’s also important to respect their decision to end communication and not pressure them into responding or continuing the conversation if they do reply. Ultimately, only reach out if it feels necessary for your own emotional well-being, but prioritize your safety and boundaries.
