The grieving actress took to Twitter to thank her fans for supporting her since the sudden death of Monteith on July 13.
"Thank you all for helping me through this time with your enormous love & support. Cory will forever be in my heart," Michele said.
The actress attached a photo of the couple hugging on a beach, both looking happily in love.
Just days after the tragic news was announced, Michele's representatives said the actress was grieving alongside his family.
The autopsy reports said the actor died of mixed drug toxicity. Monteith was trying to overcome his drug addiction problem and had come out of his second rehab trip just weeks before his death.
