question! (SPOILER)

after watching this movie, i got depressed, as a bottom gay male, i got pretty attached with johan character, and it really broke my heart when i saw the scene where johan ate the grizzly berry and witness robyn been flirting with henri, is it true that robyn is cheating from johan, or is it just me being over sensitive? and also, did robyn really leave johan alone in the forest? my sensitive feeling told me that robyn leave johan alone in the forest and go back to the farm. omg this is so embarassing but i cant help it, i need to ask this..
