Hi there,
Nice pic of dog, I also have a pic of a dog that isn't mine. I just love dogs, but happen to have 4 cats instead. (lol)
I am guessing that you are quite young. Perhaps very early 20's. Correct me if I am wrong, because I did read the post about your mother.
Those kind of text or emails are really just a baiting and fishing expedition. They try to get your attention, they wait for you to respond, when you don't they childishly say they don't know how that text even got sent out. Denial and gaslighting.
You were right to not respond. And oh, btw, welcome to our family.
((((((((((((hugs)))))))))))))
