Words for a real moment
What to say when someone feels lonely
Make the invitation concrete and easy to refuse. Consistent, ordinary contact is more useful than a dramatic promise.

Words you can use
A ready-to-send version
You have been on my mind, and I would like to see you. Would a short call, a voice note, or simply a quiet message suit you? Say yes, no, or nothing at all — I will follow your lead. If today is not right, that is completely fine.
A useful approach
Let them know you want contact without making them explain why they feel alone.
Offer a short message, a ten-minute call, or quiet voice-note company.
If they decline or stay quiet, check once tomorrow and then give them space.
Make it fit your person
Change the relationship, timing and tone
