Pretty much. The idea of Chris being in a genuine, healthy relationship just doesn't make sense with everything we know about him. I think Flutter is a weirdo who, at best, seems to be enabling Chris's delusions and, at worst, like most people who willingly choose to latch onto Chris, has their own set of issues that make this whole situation even messier. Nothing about this seems like a normal relationship, it's probably just another chapter in the ongoing trainwreck that is his life. Even if they are actually into Chris, that just raises more questions about their own mental state.
