Still pursuing in a non-pursuing manner!

I had almost forgot that my ss19 bday was this week so I sent ex an email as this:
....Hi there!
I didn't even think to ask you this last night. I know 'ss' bday is this week and I would really like to send him a card from all of us but don't have his address. Could you email that to me or can i just send it in c/o to you?
Thx. T

He replied back after just a few minutes:
.....hi it is a hot one here just sent the card to me i don,t know his ad at his house hi to all 'ex'

Pleasant and allows me to start a contact w/stepkids. I'll make the first move here and see if that makes him realize that he needs to keep up contact w/s8!

But then our anniv date is the day after the bday. Do I send anything to ex to let him know I still have good memories of that day?
