I feel like you are going to get a lot of mixed reviews with your story, but I'm entranced. What wonderful writing and descriptions of inner feelings. I've one writer here that I just read for his great imagery, which I need to catch up on. I'm so behind. But, back to you. I'd say, keep your descriptions of the relationship in a comfortable place for you and your readers. I don't mean take away from your story. Just be tasteful and make your readers appreciate your writing and the emotions you write. JMO. I love it!
