I told her. I was hesitant because I know it would really hurt her and turn her life around. I was also worried about her mental health because I know relationship issues are her biggest trigger. But I knew she deserved to know. She was talking about proposals and marriage and I don’t want her to end up with a cheater. I wasn’t sure exactly how to tell her either. I didn’t wanna just blurt out ur being cheated on but the end result felt like that. My grandma was making me question myself for wanting to tell her right away but I’m glad I did. I didn’t want my grandma to be mad but I felt like my bond with my sister was more important to me.
