Dealing with your parents divorce? ?

Hi, I'm 26, and about 2 years ago I mistakingly found out my mom was cheating on my dad. My mom and dad had been married for about 30 years, and I am pretty family oriented, so it was a pretty devastating senario for me. I told my husband right away, and we went to my pastor for advice. I didn't want to hurt my dad, so ended up knowing for about a year and a half and not telling anyone, eventually it got to a point where I couldnt live a lie anymore, and the secret was crushing me, especially when my mom would go for after work shopping trips, and my dad would wonder where she was. I got a therapist, and she walked me through what I thought was the right thing to do, which was confront my mom, and I did it infront of my Dad, as I didn't want to play sides. Now their house, my family home for 21 years, had just sold, and the divorce is in the final stages. How do you deal with this? My relationship with my dad is good, and my mom, well we talk and get along, but it all seems so fake, like there is still a big elephant in the room. She plans to date and stay with the man who she was cheating with, and he also did the same thing to his family. She has never really apologized or seen the impact this has caused. I am not like a normal kid stuck in a family divorce here, I'm grown, married, and have set boundaries with my parents, but I still feel like im floating, and it's not real. When will things feel normal again, when life with just go on? I'm trying to make my own traditions and memories, but since the separation in August, it's been tough.
