Your kids are brave to interact with clowns. I never understood their allure and hid from them.
Whoa baby.. setting deadlines, talking directly about mediation or hiring a lawyer. Did you hit the point of either/or?
I think anniversaries have a way of doing that. The day after mine, I told my spouse that I no longer had a husband and I was longer his wife. When I talk about our relationship it starts with "When I was married". That happened without me making a conscious choice. Maybe it's realizing that with his relationship and living with her, he's not here, he's not in the relationship, it's just me.
