My wife and lover send me text messages but don't return them.

This is a very difficult situation, because your lover has chosen to be with his wife, which may be painful and confusing for you.

If you receive his message, you can consider the following possible reactions:

1. Honesty: If you feel the need to respond, you can honestly express your feelings and confusion. Tell him that his behavior has hurt you and you feel very sad and disappointed.

2. Keep your distance temporarily: If you feel that you need some time to deal with your feelings, you can consider keeping your distance temporarily or not replying to his messages temporarily. This will give you some time to think calmly and deal with your emotions.

3. Delete his contact information: If you feel that you can't control yourself, or his words or actions may make you feel uneasy or painful, then you may need to consider deleting his contact information, which can help you avoid more interference.

No matter which way you choose, it is important to remember that your emotions and feelings deserve respect and attention. If you feel very sad or unable to handle your emotions, it is also very important to seek professional help.
