Is it normal my friend likely has an imaginary gf

I think one of my guy friends has an imaginary gf.
Hes always had bad luck with women. He's very feminine for a guy, not in how he looks but his personality and he lives with his mom and has no income so I guess thats why its hard.
Hes had internet girlfriends when he was younger and he and still talks about it.
A little over a year ago he claimed to now have an internet gf. He's given contradicting details about her which makes no sense. He doesnt have her as a friend on facebook. Only place i've seen them follow each other is Steam and Twitter.
I know my friend roleplays in video games a lot with female avatars and he uses a unisex name on all his socials... Anyway this girls Steam profile is the only social tied to her that seems legit due to all the activity ranging years back.
She has no profile pictures, it's a pic of an oversexualized anime girl.
She hasnt typed anything aside from her bio and it sounds identical to my friends writing style/use of words she even uses the cutesy emoji my friend overuses...Her content on Twitter is only retweets of gaming-content and the account became active the SAME MONTH my friend supposedly met her... 🤔 Their content on Twitter is the same.
The most sus thing was when him and I was playing a game and as usual he was using a girl avatar, but the thing is...HIS AVATARS NAME WAS THE SAME NAME AS HIS GIRLFRIEND... So he was playing AS HER in the game... That was weird as hell and almost fully convinced me she's made up, like that she's one of his gaming alters... I'm not sure if I should be concerned? Being in your late 20s and doing something like this is concerning but everything points at her not existing. Hes weird in general like he claims he can read peoples minds and see ghosts... Stuff like that. He's a cool guy but he's a bit special.
