Is AUTHOR wrong in the post ? POST : In December of 2017, my maternal grandmother passed away. I was very close to her. My mom was devastated as well, and so was my dad. My parents told me a month later that they were getting a divorce, and despite being in my twenties, this damaged me severely, adding to my depression. About a year ago, my mom disclosed that my grandfather had a girlfriend. Apparently, he started dating her about six months after my grandmother's death. They had been married for fifty-one years. 

I understand that he's not used to being alone, and I understand that he wants to continue to have a life. I understand that this may be best for him, and that's fine. But I don't want to hear about or see him doing as disrespectful to my grandmother. He visited my parents a few months ago, and when I visited, he was on the phone with his girlfriend and wanted to introduce me to her. He didn't ask me how I felt about it, how I felt about the pictures he kept showing me of her. He didn't ask me how I felt about the fact that she's just four years older than my mom. It made me want to claw my way out of my skin. He didn't ask me how I felt about the fact that this woman was friends with my grandmother, that my grandmother trusted her. 

I love my grandfather, but seeing this is so painful for me and I don't want to be around it, or her. AITA for feeling this way? Would I be an asshole for asking him to change the topic and not attempt to introduce me to her, as I'm not comfortable with it? What do you think?
