When your boyfriend says he's feeling cold over text, you can respond in a caring and empathetic way to show your concern. Here's a thoughtful response you can consider sending:
"I'm sorry to hear that you're feeling cold, [his name]. I wish I could be there to keep you warm and cozy. Is there anything specific I can do to help you feel more comfortable? Stay warm and take care of yourself. If you need anything, I'm just a text or call away. Sending you virtual hugs!"
This response acknowledges his feelings, expresses your care and concern, and offers your support. It also leaves the conversation open for him to share more about what's bothering him or to let you know if there's anything you can do to help. Remember, communication and showing that you're there for each other are essential aspects of a healthy relationship.
