"Rip sweet angel you will forever be missed and loved so much thank you Caleb for showing me real love and happiness ❤️❤️," she penned to her Instagram next to a carousel of photos of them together.
Tammy and Caleb met at an Ohio-based rehabilitation center and got engaged after only a few weeks of dating. They said "I Do" in November 2022 surrounded by friends and family members. However, Caleb announced back in April that they had called it quits.
Although the TLC star and the 40-year-old had been separated at the time, in the weeks following his death, Tammy opened up to her fans about her complicated feelings of grief.
"I hate getting on here and letting everybody see me like this," the 37-year-old told fans in an emotional TikTok. "Yeah, we were having problems, but I loved that man. I still do ... I miss him like crazy."
Tammy also thanked fans for their words of love and support, but clarified that she would not "get into details" regarding his cause of death because "that's really personal."
