Transcript for 'The Bachelor': Arie and Becca see each other for first time since breakup
Did it all end happily ever after? Arie luyendyk from Arizona. Down on one knee for the second time. Lauren Elizabeth Burnham, will you marry me? Definitely. Tonight's proposal comes after last night's dramatic upset. The bachelor got cold feet. After proposing to becca, the 27-year-old publicist from Minnesota. Will you marry me? Of course. Millions of viewers watched with baited breath. Driven to the brink by a shockingly callous person realizing he is really in love with Lauren. The 25-year-old tech salesman from Virginia. Do you want to be back with her? I want to see if there's that possibility. You're kidding me. That was wild. 16 years of this and that was breath taking. It will take a little time the process all of that even for myself who knew it was coming. I admit, I stayed up late to watch it. It sucked me in. Reaction to the bombshell break-up as the bachelor's swap was swift. He is such a jerk. His jerkiness came through so loud and clear. He didn't make it clear, we are done. He made it all about Lauren which I thought was really rude. Former bachelors chimed in on Twitter saying, does this mean jayon and I are off the hook now? SHAWN low saying I don't like the one bit. Last season's final rose went to Vanessa. She said you do not play with someone's heart like that. Say what you will about the bachelor, it has produced more than 20 successful couples is that plenty of children. 15 years strong and audiences can't seem to look away as bachelor cameras hang on every tear. I feel like my future was ripped away. I wanted that for us, too. And I can't give those to you if I'm in love with someone else. We're talking about a reality show. Right? So I think part of the deal is, whatever happens in these relationships gets broadcast to everybody on the show. It becomes part of the show. In some ways, there's to wrong way to have a break-up because it makes it more interesting. The bachelor host has been through his share. He said after he headed home from Peru, he started having doubts. I heard weeks after that he was still struggleling the decision and he was still fighting it. And he was very open talking about it but the things didn't seem to be going that well. Then several weeks more, he came to me and decided he was going to pull the plug and do this. He is a reality show producer's dream. If you're going to create a human being for a reality show producer, he should have said, I'm not doing this on camera. But it was extremely insensitive. She's crying in the bathroom result of knock there? No. I'm getting broken one a million cameramen around. And even it was all in the same episode, the decision to call it off came weeks after the proposal. And he said I can't fake had for another weekend. I can't go through this and look her in the eye for another weekend. And I know I really care about Lauren. And I want to give this a shot. I think one of the reasons that he loved Lauren is because she was such a weak little soul that was so dependent on him. I felt like he was carrying around a weak little bird. What we know about Arie, what he's shown us. He is an ambivalent choice, it is not permanent. I would sty this new girl, buyer beware. Glaek tried to put the past behind her. He had to do what he had to do and follow his heart. Becca face to face. I should not have pro poetsed. I needed more time but I didn't have any more time. So do you accept that apology? I do. I and I for give you. The bachelor has seen its fair share of fairy tails gone awry. I haven't ble to stop thinking about Molly. Are you going to thenld tonight? I have to. Jason famously decided to call it off with Melissa after his proposal. Will you make me the happiest man? Deciding instead to be with Molly. They have a daughter get. I've been through. This as I told Arie, Jason was back in the dark ages. There was no social media. Your life will change if you do this. Jason offered some sage advice. Don't do this unless you're 100% certain. Breaking up is now real big business. It is a $2 billion a year industry. You can download, get a break-up box or even enlist a service that takes care of the dumping for you. Amy started renew. A break-up boot camp in upe New York specifically designed to heal the heart. So they say necessity is the mother of all invention. Yeah. So five years ago I was dating someone I thought I would marry and spent the rest of my life with. When that fell apart, I realized there needs to be something for people going through this very pivotal stage of life. We were told to bring a journal. Eye S. I don't know what this is for. I'm excited. The broken hearted come here to bond with animals. You're so sweet. Meditate. You may notice there are some spots of your chest that feel pain, tightness, loneliness. And open up in group therapy sessions. This 36-year-old is still healing from an old break-up. I dated someone about five years ago. He was in it and then he would just disappear. That was just crushing for me. I want love in abundance for myself and I don't want to have fear anymore. I feel free. I feel so inspired and in control. I think I'm definitely open and toward find love again for the first time for me. I have that confidence. So I'm definitely going to bring a different type of love and a love that I deserve.
