Yeah, that's pretty much all it is. He was always a hardcore, hilariously contradictory Republican ("""""pansexual""""" crossdressing furry twink that drinks his own cum yet is anti-gay marriage, thinks climate change is "the greatest con ever played on the American people" and sides with Nazis?? Aight) thanks to his military family, so him suddenly flaking over to the left and claiming to be friends with Deo and her pals is complete crap. He hasn't changed his shitty opinions at all, he's just siding with the crowd that'll make him look better than Foxler and Friends. That's all it is, that's all he's ever done.
As for the imaginary boyfriend thing, that's a whole trip in itself. From what I'd been told, after we broke up he had multiple, very very short-lived relationships - the guild leader who dumped him because he's a creep, who I mentioned before being one. Another one I know for certain was some dude on FA who he got with, gave a shoutout to as his 'boyfriend' in one of his YouTube videos, and then his dad saw the video and flipped shit. So he dumped the FA dude because his dad was threatening to cut him off by the wallet, basically. I know Shareia's been doing this on-again-off-again thing with him, probably because of his crap, but I don't know whether that started before or after the imaginary boyfriend thing.
Eventually he decided that he would just say fuck it and invented a new boyfriend for himself named Lucas, to be the big burly guy he apparently wanted to fuck, and had even made a journal touting this new made-up character as his boyfriend because "actual interpersonal relationships are bullshit." He then proceeded to come up with elaborate stories for the character, make a ton of journals detailing said character's life and why he's so good for him, or something. I was linked to a few of those journals a couple of years back and it was a whole new level of delusion, even for him.
Also, fun fact: For the first full year we were dating, he was going by the fake name Luke. Like, legit refused to tell me what his real name actually was (which I guess should have been the first flag that I was hitching myself onto a crazytrain). So he gave his fake boyfriend his own fake name.
