Sent flowers. If no response, is it over?

My girlfriend and I had an argument last week. I gave her three days of space, letting her cool down... she's been ignoring my texts and calls. Today, I decided to send her her favorite flowers w/a little teddy bear included (her nickname is bear).

If she doesn't contact me today after this, should I just move on? I mean, it's flowers and a teddy bear... if she cannot forgive me after that, it's over, right?
