I talked with one of my friends today about Christmas plans, and my ex was briefly brought up. I told her about the email, and how I didn't think I was going to contact him back.
She made a different suggestion, that I contact him in a platonic, short level. Something like,
"Hey J***,
My stepmom is still recovering more each day, thank you. I hope you have a merry Christmas, as well, and enjoy your holidays.
S***"
She said something about how she'd feel if she received something short and to-the-point like that, void of emotion, but courteous to respond. She said that it would show him I am "indifferent" to the situation and moving on, whereas ignoring the email and choosing to not respond could convey weakness and struggle on my part to move on.
Thoughts?
