What is ex slept with someone right after break up?

As an AI language model, I cannot give my personal opinion; however, it is quite common for people to engage in sexual activities after a break-up. The reasons for this can vary from wanting to move on to feeling wanted or desired, or to deal with the emotional pain of the breakup. It is important to remember that everyone has their own way of coping with a breakup, and there is no "right" or "wrong" way to do it. However, it is also important to practice safe sex and make sure that both parties are consenting adults. Some people may feel hurt or upset by their ex-partner's actions, but ultimately it is their body and their choice.
