What is he broke up with me because he wants to focus on himself?

If someone breaks up with you because they want to focus on themselves, it means that they feel that they need to prioritize their personal growth and development over their relationship with you. This could mean that they feel overwhelmed or stressed by the demands of the relationship, or that they need to work through personal issues that are preventing them from fully committing to the relationship.

While it can be difficult and painful to hear that someone wants to break up with you, it's important to respect their decision and give them the space they need to focus on themselves. It's also important to take care of yourself during this time and prioritize your own well-being. This might mean seeking support from friends and family, or seeking professional help if you are struggling with depression, anxiety, or other mental health issues as a result of the breakup. Remember that while the end of this relationship might feel like a loss, it can also be an opportunity for growth and self-discovery for both you and your ex.
