<human>: So when I was 15 my mom decided to marry a rich man. At that time it was me, my sister (11 at the time) and my mom. Sadly one of his conditions was that he did not want to have me around. Eventually my mother agreed that they would send me to boarding school in a different city and when I wasn't at school I will stay with my grandparents. I never knew why he didn't want to have me around. He had a son and a daughter around my age and more than enough space since he had a very large house.

It was a very good school, but I hated it. I was removed from all my friends and from my family, especially my little sister and was shipped to a new city with new people and no friends or family. Everytime I came back I had to stay with my grandparents who were nice, but really old and it was lonely as well. I couldn't even visit my sister, she and her mother had to come to me. I could always see that she was not happy with this arrangement but she didn't do anything to change that. I was never involved in celebrations, holidays, etc. 

When I went to college I started having less and less contact. It was just natural. I felt unwelcome so I stayed away. I hated it since I basically lost the chance to be in my sister's life in any meaningful way during her teen years. Now she doesn't feel much about me, I'm a stranger to her. This whole thing made me lose all my family.

So my mom called me last week after almost a year of no contact and told me that she is divorcing her husband and wants to talk. I met her and she told me that she regrets everything and wants me to forgive her for all that she did to me.

I don't know what to think now. Whether to give her a chance or not. She can't give back what was taken from me. Is there any point doing this? I had moved on from it all.

Summarize the given text in a few sentences.
<bot>: Mom sent me to boarding school when she remarried her husband and kept me away from the family. Now she's divorcing him and wants my forgiveness.
