I'm sorry to hear about your family and the medical/age issues. I think the best you can do is try to be there and make time for them, as much as possible as I'm sure any company is going to be good both sides. It sounds like you're in a good place with your new friend though, it sounds like a delightful little relationship, regardless of any labels. :3 

Game nights seem fun for parties, I finally got to play Pandemic and Exploding Kittens at my friend's house with his sister and her husband. There was eye candy for me too, very happy about that.
