It's always going to be an uphill battle for a couple to make things work after someone cheats.
And for Robert Pattinson, 26, and Kristen Stewart, 22, who are trying to reconcile their relationship after she cheated with married director Rupert Sanders — it's proving to be quite difficult because RPattz is finding it hard to rebuild the trust he once had in her.
"The love story between Robert and Kristen is still a bit of a conundrum; it's a weird relationship," an insider close to the couple told RadarOnline.
"Despite claims that all is rosy, he's still not completely convinced that giving their relationship another chance is the right thing to do. For one, his family and friends are totally against the idea — and although he's his own man and makes his own decisions, there are times when he thinks they are right.
"And there are moments when he continually asks her questions about the affair, so it's all still very tense. They have some really serious trust issues. But they were brought together again by a great friendship, so there could be hope. Robert thought Kristen was the girl he was going to marry.
"However, that's all on hold for the moment until they try and work things out. This could go either way."
The Twilight actor's friends apparently don't believe the reconciliation with his co-star and lover of four years will last and the pair will only stick it out until the promotional tour for Twilight Saga: Breaking Dawn — Part 2 ends later his year.
"Rob believes that Kristen didn't sleep with Rupert Sanders, but the fact is, she still cheated on him," the source added.
