Easy

When things become too easy for the both of you. When there is no challenge whatsoever. Life is just no life without risks and challenges. It becomes dull and uninteresting without the two. Sometimes you could feel yourself trapped in this so-called affinity. It's like your market dropped down drastically. And that's as if you were that high in the market. You see, you miss the challenges and being stuck between things you couldn't do to get what you want. Because with that, you just have to try harder, try new ways to get it. You've been through that. But now when you already have it, you thought, is this just it? Is this all?

The worst part is, you're starting to lose faith in your future with him. Nevertheless, this is not an affinity, you have clearly stated that. You are still only mates and no more, as you've wished to.
