Partner says loves me as brother and moves out

[Mumin]

If there are some things she really likes and she paid 50% its fair that she gets/buys some of them.
See it as a business transaction.
That transaction could of course bee that you keep everything and pay her. Depends on the items and whether she likes them or not. Second hand may be cheap but some things can also be one of a kind.
As said, do what is fair.

To be clear, we are not defending her here. Just giving advice on what we have learned on this forum and in our own situations.
