Mum-of-one Kim Jenkins,33, with her friends and family, had been raising cash to pay for therapy currently not available in the UK - but available in Germany.
She had exhausted all other treatments in the UK after being diagnosed with a rare and aggressive form of breast cancer when her daughter Miya was just three-months-old.
Sadly Kim cruelly lost her battle at home late last night - and her death was announced by her family this morning.
Her heartbroken partner Tom - father to two-year-old Miya - said this morning: "I am a broken man and have lost half of my existence.
"I feel her close to me all of the time, but it's hard being in love with someone that is behind the reflective fabric of life."
The couple had postponed their wedding last summer as the cancer took its grip.
She and Tom were planning to get married in August last year, but they were forced to put the wedding on hold after she found a lump under her armpit and underwent further treatment. May her soul rest in peace.
