If you believe all of this is going on, and this is the behavior she's displaying, why on earth would you want to send her FLOWERS on her birthday?
Totally "PURSUING." A funny Shoebox card and a modest, practical gift like a gift card inside of it, that she can use for something, would be my recommendation.

I'm in no way disagreeing with the Great One, Puppy, but I think it's a good move, the flowers. See, he doesn't KNOW ... but he's checking it out with the secret drive-by to Mom's. And at the same time, he's got a parallel deal going on whereby he 180's her with flowers - something he would not have done in the past. Isn't that holding both thoughts/objectives in his mind at the same time? Now...if he finds out that she is not at Mom's ~~~ then, yeah ~ no flowers of any description should be sent. But right now - wouldn't that be ok?
