When "Twilight" stars Kristen Stewart and Robert Pattinson's break up became public many rumors spread about what caused the split but despite what has been said the reason behind it is continuously blamed on the actress.

In their latest break up news reports are alleging that the actress scared her 27-year old boyfriend away with her constant marriage demands.

Following their 2012 break up, when her affair with married "Snow White and the Huntsman" director Rupert Sanders came out the couple got back together. However when they reunited Stewart expected to pick the relationship back up where they left it.

According to Perez Hilton, a source revealed the "On the Road" actress' intentions, "Kristen wanted to go straight back to where they'd been before they first split up [in July 2012] and pushed Rob really hard on it.

"She wanted the whole package: the house, the wedding and even the baby. It was all way too much for Rob to handle.... [It] sent him running for cover... Rob asked for space and it sent her over the edge. She told him if he wanted a break, it would be permanent."

Crossmap reported that when the actress turned 23-years old back in April she told friends that she was certain about her future with the actor, "Rob and I will get married."

It is rumored that the actress grew too dependent on her off-screen love and the actor became frustrated playing the role of parent to his girlfriend.

A source said, "through the years, Kristen definitely became too dependent on Rob saving the day and taking her back."

"He felt like an adult taking care of a child," the source explained.

"He's glad to only have to be in charge of himself... He thinks she has a lot of growing up to do."

Now that both stars are single Stewart has been surrounding herself with good friends, "Kristen has been doing her best to keep busy now that Rob is no longer in the picture. Her friends have been by her side 24/7. Over the long weekend, they spent lots of time in Silverlake, where her younger brother lives."

Meanwhile her ex-boyfriend has been spending his spare time with singer Katy Perry but a source told E! News that they are just friends, "Nothing is going on between Rob and Katy."

"They are just super good friends. There is nothing romantic in it."

"Rob and Katy are just very similar people and she adores him, as a friend, and she just wants to be there for him as a mate."

According to Crossmap, the actress is not upset with by the news that Pattinson and Kay Perry have been spending time together, "Kristen isn't upset with Katy Perry because she doesn't think anything romantic is going on between them."

The source told E! News that since the break up, the Hollywood heartthrob has got a handle on it, "Rob is doing fine since the breakup."

The source said, "He is not particularly cut up about it or anything. He is doing just fine."

It is reported that this is the longest amount of time the couple has not spoken to each other.
