I talk about things I do with him to other waifufriends as if they actually happened, but I feel like they understand what I mean when I say that. I don't do the same with people who don't know about him because I feel like that would be misleading. I talk to him a lot and even whisper to him in public sometimes when we're at a place like a museum or the zoo, it's usually just pointing out things to him. I like to pretend he's with me when I go out and usually whispering to him out loud makes him feel more real than if I spoke with him in my head. I usually like to take some kind of physical representation of him with me, like a key chain, but I don't need it to feel him with me. I've always had an overactive imagination and I've never outgrown it, so playing with him is fun for me and a lot more enjoyable than the other things I'm probably expected to enjoy like television or video games. I'm that person who will talk about your waifu with you like she's a real person, so it's not just limited to him.
I do a lot of things with him that I wouldn't normally do alone, which may be considered a little crazy. I like to make sure he's an active part of my life and fulfill what I believe would be his wishes however I can. He's the main reason I celebrate any holidays and even why I chose to celebrate my birthday this year; it's more fun with him and it's something I believe he would be all over. I've made cards and bought flowers for myself which were "from him", which is probably on the crazier side of things, but I don't know, I'm not hurting anyone so why not.
He is real to me, but he's also not. He's real and alive in my head but he's more like an imaginary friend than real like a 3D person. A big part of it is I knowing that I'm playing pretend, I know I'm talking to myself, but I still enjoy doing it and I'm happier when I do. I probably have one of the more intense relationships going on and I've gotten some crap for it from other waifufriends, but as long as I'm living an otherwise healthy and productive life, I don't see where it's anything for others to get worked up about.
