I'm 28 and the youngest of three children. My siblings and I had a challenging childhood; our dad disappeared from our lives when we were little, and our mother suffered from severe depression. My sister, the eldest, took on the responsibilities of taking care of my brother and me, even though she was only a few years older than us. As early as middle school I started to rebel, and I ended up getting into drugs and a series of abusive relationships later on.
In the process I also managed to completely alienate my sister. She was always there to help me, and I was always pushing her away. Some years ago, I did the unthinkable and hooked up with her boyfriend at the time — a man she was very in love with. She was destroyed, but she said that she knew it wasn't me. She told me she'd let it go if I checked into rehab, which she offered to pay for. After much begging, I agreed to go. But within a few weeks I left, and ended up costing my sister thousands of dollars. By that point she'd finally hit her limit, and told me she wanted me out of her life.
It's been five years and we haven't spoken, though I'm still in touch with my brother. I've cleaned up my life significantly, and I have a stable job for the first time in my life. My sister recently had her first baby, and I'm desperate to see them. But when I told my brother I was going to reach out to her, he told me not to because he doesn't think she'll be willing to see me. I know I've done some bad things, and I know I'm still imperfect, but don't you think my own sister should be able to forgive me?
