I have been with my OH for two years. We live apart for a number of reasons and see each other at weekends and during holidays. We are happy together. A number of times we have borrowed cash off each other (between £20 and £100) to pay for unexpected stuff if we had no cash (or not enough cash) on ourselves. We have always paid each other back within a week or two. No issues whatsoever.
A month or so ago I ordered some boots he wanted to get for his brother for his birthday. He doesn't have an Amazon account so I offered to order them on his behalf (they cost around £150) and to have them sent directly to him, my OH. The boots arrived, his brother liked them, all good.
However my OH has since forgotten to pay me back - to be honest, until this morning I had forgotten all about the money myself. Because we only see each other at weekends, unless we remember then, another week will pass by before we can pay each other back. And the longer we forget, the less likely we'll remember. So how can I gently remind my OH about this money? Neither of us is hard up but £150 is still quite a bit of money for both of us so I'm keen not to 'write it off.' Any ideas? Thank you.
