Fletcher had to make another heartbreaking decision on Monday

Spoiler warning:

For those who haven’t seen Monday’s episode of The Bachelorette, plot details follow.

The chemistry between JoJo Fletcher and Southern gentleman Luke Pell practically jumped off the screen, but shockingly, Fletcher bid a tearful goodbye to Pell on Monday night’s episode.

“I struggled with that decision,” Fletcher tells PEOPLE exclusively. “But having him pull me aside to tell me he loved me, that threw me for a loop. I was so overwhelmed with every emotion that you think of.”

The 25-year-old real estate developer, who will face Pell, 31, for the first time since their breakup at The Bachelorette: Men Tell All on Tuesday night says she “didn’t know” if she made the right decision initially.

“It was hard. I could have changed my mind, but I also knew that could have been an impulsive, emotional decision so I tried to stick to what I thought was right. I told myself if I woke up the next day and felt like I regretted it, then I would call him. The next day I was sad, but I trusted my gut.”

The Bachelorette: Men Tell All airs Tuesday at 8 p.m. ET, and The Bachelorette‘s finale airs Monday at 8 p.m. ET, both on ABC.
