Do you think is the right thing to do? I dont eant her to think Im weak or to feel bothered I just want her to feel appreciated and propably even realise she shouldnt have acted that way I deserved a closure at the very least
This says this is all about you, and not at all about her.
You can wish her the best....privately.
I’m sure there is much more to the break up of your friendship than you are saying here. I really don’t care what the story is. Neither does she anymore.
Sending her flowers, or even a note, is only going to annoy her, and make her wish you’d give it a rest already. Don’t use an unrelated event, such as this to make another unwelcomed attempt.
You need to move on. She has.
