This is a tricky situation, but it can be handled in a few steps:
1.Communicate openly and honestly
First, you need to be honest with your ex-girlfriend about why she can't continue to live in your home. Express your position and feelings, but remain calm and respectful.
2.Set a clear deadline
If she has an emergency or has nowhere to go for a while, she can be given some time to prepare to move out. But make sure you make sure you don't delay by telling her about the deadline for moving out.
3.Ask for help and support
If possible, seek the help of a friend or family member to provide her with temporary accommodation to provide her with a transitional place to live.
4.Help
Support can be provided, such as helping her find a new place to live or sorting out her move. But be careful to avoid over-involvement.
5.Maintain borders
Be firm in your communication and stick to it after the move-out period expires. Don't be swayed by your feelings and stand your ground.
6.Self-preservation
Ensure the safety and protection of yourself and your family during this process, especially if the situation becomes tense or unstable.
This is a sensitive and complex situation, but dealing with it firmly and staying calm is key to solving the problem.
