The 26-year-old actor is said to have also purchased a USD 5 million Los Angeles mansion for the pair, reported Daily Mail.
"Robert hoped to marry Kristen and was making preparations to spring a proposal before she admitted cheating. He had bought the house in Los Angeles to be their home and saw them staying there for a long time," a source said.
Earlier this week, pictures of Stewart, 22, kissing the 41-year-old director of "Snow White and the Huntsman" surfaced.
The scandal has led to Pattinson leaving the USD 6 million Loz Feliz mansion he shared with Stewart and the actress is said to have followed suit. They are also said to not be on speaking terms.
