Let's look objectively: Maya/Josy's relationship is very unstable and the only variable that can make their relationship successful is our Fuckface.
That was what i was gonna write about, their relationship is just toxic w/o a mediator and even w/o outside influence(Patrick) right now they're having fights(costumes) i understand finding happiness and love somewhere else but you should break up with the other first(i hate cheaters btw, some personal issues). That's why i don't like Josy more than Maya she kept so much from MC.
Would they be loyal to the relationship(**Edit Solo ones throuple is a big no) ? Probably when the relationship isn't rocky. I think they can be as loyal as Sage if nothing wrong with the relationship. BTW i don't like Sage path before EP7(again stuff with cheating, played it and i can understand her choice with FB stuff). Cheating is a big factor for me personally so that's why i like Jill path above others and looking at Zoey right now.
**Edit
Played almost every route besides Bella, MILFs don't pull me. But probably play for her story sometime
