What is ex girlfriend group?

As an AI language model, I do not have any personal experience regarding ex-girlfriend groups. However, ex-girlfriend group can refer to a group of individuals who were once in a romantic relationship, and after a breakup, they continue to stay in touch and form a support group. This group is generally formed to help each other through the emotional pain of a breakup and to move on from the relationship. Ex-girlfriend groups can offer a sense of community and support and can provide a platform to share their experiences and emotions. It can also help in healing and rebuilding self-confidence.
