Man, that's tough. Gut wrenching to read. My kids were super young and now-ExW told them without me even though we agreed to tell them together. Did your daughter know something was up? Sounds like she took it almost too well? Maybe she's "being strong" for mom and dad, which isn't great either. Good you'll get them into counseling.
How are YOU doing? You mention temporary relief, but now that time is passing? Are you alright?
