You know why you did it, and frankly it's not bad. You know what would freak her out? Picking up the phone, giving it to her and saying nothing. Your reaction was actually not bad at all, and seems like it really scared her. But she's still spinning mentally and has no idea what she wants.
But, if YOU don't feel in a good spot mentally that's what you need to work on. Calm down, take it a moment at a time. Going NC might be a good idea for you, it'll get you to focus inward again. Keep doing fun stuff with your boy!!

Cheating on a good person is like throwing away a diamond and picking up a rock.
