As far as a response goes, I would acknowledge the apology and tell him that you appreciate it. That is what I said to my XW.
Somehow saying "Thank You" does not fit........I don't really say thank you to something I expect......and as unhealthy as it might sound, I think we all do "expect an apology" one day.
I think something along the lines of......
XH, I carefully read your last email and what you had to say. I appreciate your apology. As far as my sympathies go it is something that I would say to anyone that was sharing their feelings with me. You keep the mug, needlepoint and etc etc. they are yours.
Less is more here.
I think I would continue to engage him as long as it does not hurt you. That is a fine line for sure.
I will tell you that tonight I was a little more "friendly" with my XW tonight when she came to pick up my son.
It is definitely easier with the apology behind us, I however feel that there might be more to come.
You are doing well, just keep moving forward with your life.
Cheers

Expose yourself to your deepest fear; after that, fear has no power, and the fear of freedom shrinks and vanishes. You are free.
