My girlfriend blacked out my mobile phone WeChat and ignored me for more than ten days. What should I do?

First of all, you need to think calmly, why does your girlfriend do this, and what kind of result do you hope to get.

If your girlfriend is angry or dissatisfied, you can try to contact her through other channels, such as calling, texting and social media. Apologize to her and express your apologies. You can also write a sincere letter to express your feelings and hopes and ask her for forgiveness.

If your girlfriend doesn't explicitly break up, then you can try to communicate with her and understand her thoughts and feelings. You can express your concern and love to her and ask her if she would like to continue dating.

No matter what action you take, you should respect her decision and feelings, and don't force her to accept your contact and apologize. Give her some time and space to think calmly and adjust her mood.

Most importantly, you should seriously reflect on your behavior, see if there is anything that needs improvement, and try to be a better partner.
