R-Pattz has a deep attachment to Twilight co-star Kristen
The couple sparked rumours of an engagement when they were spotted shopping for rings at West Hollywood jewellery store Neil Lane.
Rob takes love very seriously and has spoken in the past about not being a ‘casual-affair kind of guy’.
Kristen‘s confession to cheating with married director Rupert Sanders, 41, has destroyed his world.
A source believes the Twilight star, who shared a home with Kristen in Loz Feliz, LA until he moved out his week, was planning to get down on one knee at the end of summer.
‘Robert hoped to marry Kristen and was making preparations to spring a proposal before she admitted cheating,’ the insider claims in the Mirror.
‘He had bought the house in Los Angeles to be their home and saw them staying there for a long time.
‘Now Rob is angry – he’s left the mansion and not spoken to her since. They have exchanged heated text messages only.’
R-Pattz, 26, met Kristen, 22, when he took the role of vampire Edward Cullen who falls for Bella Swan in the Twilight films and it was an instant attraction.
‘It is true that Kristen has always done something to me that others haven’t,’ he told BlackBook magazine recently.
Robert and Kristen will be obliged to reunite at the premiere of the final installment of the The Twilight Saga: Breaking Dawn – Part 2 in November.
