It is natural to feel confused and hurt when someone you've had a past relationship with comes back and cries after you choose not to get back together with them. Several reasons could explain this behavior:
Regret and Realization: The person might have realized their mistake in breaking up with you multiple times and now regrets their decision. They might have come to appreciate your value and the positive aspects of the relationship they had with you.
Fear of Loneliness: After the breakup, they might have realized that being without you leaves them feeling lonely and empty. In their emotional distress, they may seek comfort and familiarity by trying to get back together with you.
Ego and Rejection: Rejection can be difficult to handle, especially if they initiated the breakup themselves. Their ego might be hurt, and they could be crying as a reaction to feeling rejected or unwanted.
Dependency and Comfort: They might have developed a dependency on you or the relationship for emotional support and comfort. Losing that emotional anchor can be overwhelming and lead to tears.
Manipulation and Guilt: Sometimes, people might cry as a way to manipulate your emotions and make you feel guilty, hoping it will sway your decision.
Lack of Closure: If the person is struggling to find closure or come to terms with the end of the relationship, they might express their emotions through tears.
Regardless of the reasons, it's important to prioritize your own well-being and make decisions that are right for you. If the relationship has been unstable with multiple breakups, it might not be the healthiest choice to get back together unless both parties address the underlying issues that led to the breakups in the first place.
It's essential to communicate openly and honestly with the person about your feelings and boundaries. If the situation becomes too overwhelming or unhealthy, consider seeking support from friends, family, or a mental health professional to help you navigate through it.
