Pattinson, 26, was heartbroken after the actress cheated on him, bringing their three-year-old relationship to end. However, the two have decided to meet each other after the latter persuaded him a lot.
"They talked (on the phone) for about an hour. It was very emotional... Kristen begged to meet face-to-face so they could talk. It was obvious she was getting through to Rob and he has agreed to see her," Look magazine quoted a source as saying.
Pattinson, is unable to ignore his feelings for the actress whom he met on the sets of 'Twilight' in 2008 and the two had been together since.
"Even though she made a horrendous mistake, Rob can't just switch off his feelings. He was madly in love with her and I think believes that it was a moment of stupidity, not a long, drawn-out affair and it'd never happen again," the source said.
"In Rob's eyes, Kristen was seduced and she's clearly not just sorry but completely destroyed by what she's done," the source added. The two have not faced each other after the news of Stewart's affair with director Rupert Sanders broke.
