As a family law attorney, there are a few reasons why I might stop representing a client:

1. If the client doesn't work with me or doesn't give me the information I need, it makes it hard for me to help them.

2. If the client doesn't pay for my services, I might have to stop representing them.

3. If the client lies to me or doesn't tell me important things, it makes it tough for me to help them.

4. If the client does something wrong or against the law, I might have to stop representing them.

5. If there's a situation where I have a conflict and can't represent the client fairly, I might have to stop helping them.

Every situation is different, and I would carefully think about it before deciding to stop representing a client.
