A week after my girlfriend broke up with me, she sent a message asking me how I was doing. What does she mean?

It is difficult to determine what she means, because it may depend on her personal circumstances and motives. However, some possible explanations are as follows:

1. She may want to make sure whether you are still sad or have recovered your balance. She may feel guilty or want to keep in touch, so she asks about you.

She might want to come back to you. She may realize your value and want to start a new relationship.

She's probably just asking about you out of courtesy. Although you have broken up, she may still want you to live well.

No matter what her motivation is, you can consider giving her a polite reply, telling her that you are doing well and thanking her for her concern. If you want to start a new relationship, you can put forward this idea, but if she doesn't have the same idea, you need to respect her decision.
