Hello my fellow ESFJs! :) Just curious, if your friends broke your trust, would you still be willing to give them another chance?

An ESFJ friend of mine and I were talking, and she said it's really hard for her to trust her friends now because they broke her trust. She wants to give them a second chance, but she can't bring herself to trust them anymore because they abandoned her at one of the darkest points in her life. They've apologized and all that, but she still doesn't believe that they will stay with her if the going gets rough again. She's a super loyal person, and it takes a lot for her to open up and trust other people. So this is super hard for her. What would you do in her situation?
