this ask made me laugh cuz the implication is that he's incapable of having any healthy personal relationship 😭😭 c'mon have some faith in him... but seriously, i think it depends? if we're talking canon arle, i do think he can manage to improve if he were to be in a romantic relationship, i think he'd be a great partner in a lot of aspects, but he's still flawed like everyone else. if we're talking fanon arle however... my arle, for example, he's pretty much a fucking weirdo, even when he's not Extreme Arle™ (rapist/sexual offender), he's still obsessive and insane and unhinged... my conclusion is that his only truly healthy ship could be with clervie who's 1) dead and 2) would've still been a codependent partner, i think.. with them being childhood sweethearts with a shared horrible past
