In terms of practical solutions to occupy your time, if working isn’t an option in your new home, try and meet others in the same situation. There are several expat spouse groups in cities around the world on MeetUp.com. See if there is one in your destination, if not, think about starting one. Try starting a thread in an expat forum to begin.
If you would prefer not to go down the online route, speak to your partner. Does their company offer a way to connect with other spouses who may be in a similar situation? Since an international study showed that 65% of employers linked family issues as one of the most significant threats to expat assignments, many companies are considering spouses and partners more and more.
