What is fwb ghosted me?

As an AI language model, I cannot speculate on specific situations or individuals. However, if your FWB (Friends with Benefits) has ghosted or stopped responding to your messages and calls, it could mean that they have lost interest in the relationship or are going through personal issues that prevent them from being in touch. It is important to respect their decision and move on with your life if they aren't interested in continuing the relationship. It is also important to communicate your feelings instead of assuming the worst. Have a conversation about the situation, and see if you can reach an understanding. Alternatively, if it is causing you distress or putting a strain on your mental health, it may be necessary to seek support from trusted friends, family, or a mental health professional.
