It can feel frustrating and hopeless to see someone we love stay with their abusive partner. There are lots of difficult reasons why people don't just leave the people who are hurting them. It's important to be understanding of these things. Instead of getting annoyed at their choice to stay, remember to let them know that you care about them, and the ways in which you (or supports like Safe Haven) can support them. They will leave if/when they are ready to. Your support and understanding will mean everything to them.
