What does it mean for boys to use black and white heads after breaking up?

When using a black-and-white avatar, there are usually the following possibilities:

1. Express grief: If your boyfriend uses a black-and-white portrait soon after breaking up, it may indicate that he has been hit hard and depressed in this relationship. The black-and-white portrait may reflect his sadness and loss.

2. Show attitude: Black and white headshots are sometimes used to express a serious attitude. If your boyfriend wants to express his determination to break up, or wants to show that he is going through a difficult period, then using a black and white avatar may be one of his ways.

3. Artistic style: Some people may use a black-and-white head portrait because they like its visual effect. This choice may have nothing to do with breaking up, but a reflection of her boyfriend's personal aesthetics.

4. Coincidence: Finally, using a black-and-white avatar may be just a coincidence, which is not necessarily directly related to breaking up.

In this case, if you want to know his specific intentions, you can try to communicate with him and understand his thoughts and feelings. Remember, communication is the key to building understanding and trust.
