Should I forgive her?

My sister in laws accused me of cheating on my husband about two years ago. To the point where I almost lost my marriage and ended up in a hotel room for a few nights. I was so distraught I couldn't even go into work for a few days. We had just gotten married too and hubby said some prettt hurtful things to me. Didn't want to go to my parents because I did not want them to get stressed. My husband eventually came to take me back and we've been fighting ever since. I did push him once because he was accusing me of cheating but it was just to get him out of my face. That's how bad our arguments are because of what they did. Other than that, we were perfect. I was so desperate that I paid for a lie detector test. Made my sister in laws choose the company and attend. Turns out I never cheated. This past weekend they came over for a "family meeting"'to patch things up. They apologized and cried, talking about how they wanted to be in their unborn nephews life and asked for forgiveness. I told them, You guys hurt me really bad and put me through hell, I'll think about it etc... this morning the older SIL texts me talking about brunch on Sunday. I don't know how to feel and still trying to get over the hurt. I havent responded and was just gonna tell her no. Should I forgive them???
