Update: My stepdad(M40) and I(F20) play video games together and my mom(F46) is feeling left out.

Update to this post
Edited for better clarity.
Update: Things have been really good since I made my last post!! My mom and I sat down and made plans to get some board games, that are 2 player+, so we can all play together, even if someone is out of the house. She is also considering picking out some video games that interest her so she can learn the system, and is open to trying my games out as well. My stepdad and I have been individually hanging out with her on her time off.
I wanted to also follow up on a question I received on my previous post about if she was truly feeling left out: I could tell just by her demeanor that she was a bit distant during the time that my stepdad and I played games together. But also, I think I may have been projecting my own feelings and maybe making the situation worse than it was, since I will never know how she truly felt. This question really made me think about the deeper aspect to the situation, and as I said before, my mom is my best friend. I came to realize that I was also feeling a bit disconnected from her and missing her presence. It?s perfectly fine to have our own hobbies individually but in this case I think there was just prolonged isolation that led to insecurity, from my own side at least.
I can?t say that the situation is perfect and resolved yet but there is definitely progress being made! And that is relieving. I?m excited to have these future bonding times as a whole. Thank you to everyone who weighed in and took time out of their day to help me out. It truly means a lot.
TLDR; We made plans to hang out together more. Thank you.
