How to thank a partner when an arrangement ends
Thank them for the person they were, not the money. Name a trip, advice or a hard week they helped you through. Two sentences. Do not invite them back.

A specific thank-you makes a clean ending easier to accept. Tell them what they gave you, say it meant something, and stop. Two sentences is enough. It closes the door without slamming it, and lets them remember something real instead of the end.
Why thank them at all
An arrangement that ends leaves two people holding opposite feelings. One might have wanted to keep going. The other has moved on. A thank-you does not change that. What it does is let the person left behind know their time mattered to you. That makes it easier to let you go.
A simple goodbye reads as relief. A thank-you reads as respect. The person on the other side of that message remembers you differently depending on which one you send.
A thank-you also closes the chapter cleanly for you. It is the last word, and you get to decide what it is. You say what mattered, you say it was real, and then you both move forward without wondering whether the other person thought any of it meant anything.
Thank them for what they gave, not what it cost
Do not thank them for the money or the gifts. Do not say "thanks for putting me through university" or "thanks for paying my rent". Money was the way the arrangement worked, but it was not what mattered to either of you.
Thank them instead for the experiences they made possible, the advice they gave you, the time they spent with you during a month you were falling apart. Thank them for being patient when you were learning what you wanted. Thank them for the person they were with you.
The two-sentence rule
Write one sentence that names something real they did or gave you. Write one sentence that says what it meant. Send it, and stop. Do not add a second message. Do not invite them to anything. Do not ask to stay in touch.
More than two sentences turns a thank-you into something it is not. A paragraph starts to look like you want to keep arguing about the ending. A second message looks like you are hoping they will change their mind. Let the thank-you stand alone.
The brevity is the point. A short thank-you says you are moving forward. You are not hung up on the ending. You are not asking for negotiation or a second chance. You are simply marking what this person meant to you and closing the door with kindness.
Scripts by scenario
These are examples. The details matter. Name the trip, the piece of advice, the specific week. A thank-you that could have been sent to anyone reads as empty.
That trip to Thailand made me braver than I thought I was. I'm going to remember that you believed in me before I did.
Or:
You got me through the week my brother was in hospital, even when it was the last week of our arrangement. I won't forget who you were then.
Or:
You taught me how to say no and keep my own respect. That changed how I move through the whole world, and I'm grateful.
Or:
I was scared the whole first month and you noticed and slowed down. That mattered more than anything.
Or, if you are ending it:
I got what I came for and you let me leave clean. Thank you for that, and for who you were the whole time.
What you are not saying
Do not follow the thank-you with an invitation. Do not say "let's stay in touch". Do not offer a coffee or a drink. Do not suggest that you will date again in a year. The thank-you ends the arrangement. Anything after it re-opens it, even if that is not what you mean.
When someone reads your message, they need to know it is over. If you add "but maybe we could", they spend the next week hoping you might change your mind. That is not fair to them. A clean break is kinder than a maybe.
If they reach out later and you want to see them, that is different. You can answer then. But do not add that opening to your own goodbye. Let your thank-you be a full stop, not a question mark.
Saying it to a generous member
Most arrangements end because one person is ready to move on. You might be the one who wants to stay, or the one who is ready to leave. Either way, a generous member made a choice to spend money and time with you, and that is something. Tell them so.
They might respond well, or they might not respond at all. Either way, you have been honest and kind. That is yours to keep.
If they do not reply
Let it go. A thank-you is something you send because it is the right thing to do, not because you are owed a reply. They might be too hurt to write back. They might be moving on faster than you are and a thank-you from you does not help that. Or they might simply not want to extend the ending.
Silence is an answer. It does not make your thank-you wrong. You ended an arrangement and you did it well. What they do next is theirs to decide.
