I've read the whole thread now, not just little parts here and there (as was the case prior). I'm thinking she's probably a new model who has model anxiety and finds you a soothing and comforting presence in her room.
Her thinking she loved you, back when that happened, is a bit concerningly naive and not the most emotionally mature. However, I don't think that's uncommon at the beginning. To be frank it happened to me my first few months too and was really emotionally painful.
It seems like over time you have both gotten to a more balanced place, and less of an impulsive highs and lows type deal. In this context, I don't think the flowers are too big of a deal, as long as you're at a point where you are not overspending, or neglecting your work responsibilities for this friendship. Are you at a point now where you are no longer neglecting your work responsibilities?
Wait are we saying here that there is a rendition of your face sitting there at all times she's streaming, watching the other dudes jerk off?
