"I deadset thought 100 per cent that I was going to win, that I was going to be ending up with her," the 27-year-old told 10 Daily.
"When I first went in there I went in with an open mind, I actually didn't think it would happen. Next thing I know I was swept off my feet."
Tim went on to reveal that he hasn't seen the woman he fell in love with since she broke his heart on national TV.
"It took me a fair while to process what actually happened and then you don't see her again. You have this whole experience together and I haven't seen her again, do you know what I mean? It's f*cking heavy."
Extraordinary and despite his heartbreak, Timm reveals that he want to return to reality TV.
"I'd definitely be open to doing something like ['The Bachelorette'] again," Timm revealed.
"Although it didn't work out the way I wanted it to, it was definitely one of the best times I've ever had in my life. A hundred per cent open to doing something like it again."
We might be seeing more from Timm in the future!
