To what will it lead if I write to him?

If you write to him, the exchange ends more cleanly than it opens — this reads as a letter that finishes a conversation, not one that starts something.

What the three seats say

• Past — The Magician, upright. The words already exist. You have the language for this; the skill isn't the problem, and neither is nerve.
• Present — Ten of Swords, upright. The conversation is already over and already hurts. Whatever gets said now lands on a conversation that has stopped functioning, not one still in progress.
• Future — Ace of Pentacles, reversed. Under that condition, the outcome is a seed that doesn't take: something small gets offered or you hold something out and it quietly doesn't land. Not a door — a thing left on the table that neither of you picks up.

The spread is honest about a limit: no seat here is his head. These cards show the shape of the exchange and what your half does inside it. What he feels or whether he writes back is not something any card can hand you — and the future seat is a tendency under the condition below, not a prediction.

The check that decides it

Draft the message and read it once for one thing only: does it end something, or does it exist to be answered? If it closes the thread — clear, decent, no door left open — this is the letter that lets you stop waiting, and the Ace reversed just means the last little piece of hope gets set down rather than cashed in. If you catch yourself rewriting it to soften, to be liked, to be answered, then the writing costs you the thing the Ten of Swords already spent.

Action, before you send anything: go read the actual thread — the date on his last message and who spoke last. That timestamp is real evidence the cards don't have, and it will tell you more than any re-reading of your own draft.
