These are long, and there were more exchanges of this kind earlier this year. My DH writes very well. Not that it helped him - things broke down, and we have not had contact with OSD since spring. Her siblings disinvited me and then DH from their graduations in the summer. The court case with BM is ongoing. It's war!

See if you can relate - or if you can use this to prevent similar escalation.
