Your novel sounds intriguing. Novels based on relationships that incorporate different genres like yours are my favorite.
I’m also writing a novel about relationships that incorporates different genres but unlike yours, mine is told from one girl/woman’s pov. I categorize mine as Women’s Fiction because it covers several different types of relationships and doesn’t really have a main genre. Because of that, I’m thinking your novel might fall into the Women’s Fiction genre.
If you’re still looking for a beta reader, I’m interested and would love to help you. I prefer reading in chunks and I’m good at cohesive and finding plot holes. I have about 4 yrs of critique experience and give honest yet constructive critiques.
