>>82151625 (OP)Is she your girlfriend, wife, partner or something similar that's more than a friend or work-mate? Then get her some sunflowers.
If she isn't your girlfriend or wife or whatever-else, get her sunflowers and ask her out.
Clearly she wants you to get sunflowers, why else would she mention them being her favorite directly to you like that? At the same time, don't just glorify her feelings of gifting her shit unless she'll make it worth your while. Hence why you'd ask her out if you weren't already together.
And if she says no, or is dating someone else, but still wants those flowers? Then she's just using you, bud.
