Peter Kraus made it all the way to The Bachelorette's thirteenth-season finale.

Peter, a 31-year-old personal trainer and business owner from Madison, WI, is still in the running for Rachel Lindsay's heart going into the last episode of The Bachelorette season, along with Bryan Abasolo and Eric Bigger.

Peter will have to drop all of his walls in order to get to the place where he feels ready to propose, but Rachel is beginning to worry her romance with Peter may not work out because she's expecting a proposal at the final Rose Ceremony in Spain.

Rachel made it known she doesn't want to end The Bachelorette process with just a boyfriend. She's looking for a husband to settle down with, but will Peter be ready for that type of commitment given his fears, doubts and concerns about a quick engagement? Who will win Rachel's heart?
