Rapid descent

So ever since Ziggy got back, he's been different. Little things, like I've mentioned before. But it seems to be compounding, and progressively getting bigger. And when I asked Ziggy about one in particular(and a fairly personal one at that), I get this answer that boggles my mind. The answer was so completely opposite of every action that it threw me way off my bearings. To the point I am wondering something I never thought I'd ever suspect of Ziggy.......Could Ziggy have slept with Kat while deployed?

The very thought of it's being possible runs chills through me that I haven't had in years. Tears try to well in my eyes, and part of me feels as though everything that I have been holding dear and of value between Ziggy and I is unravelling with the speed of bullet train. I never ever thought I'd come to suspect this of him. But like I've said, there have been little things that keep adding up and pointing to it. I keep thinking that maybe I am overreacting, jumping to conclusions. I am trying to keep myself calm, but it doesn't seem to work. .......I feel as though my whole world has begun to crumble........
