New York, Sep 11 (IANS): Model Liberty Ross said she didn't leave her house for seven weeks as she tried to deal with her husband Rupert Sanders's affair with actress Kristen Stewart.

The 33-year-old appeared on the catwalk to showcase Alexander Wang's Spring 2013 collection at New York Fashion Week and looked confident on the catwalk, reports contactmusic.

"I hadn't actually been out of my house for seven weeks so I was really anxious. But it felt amazing," she said at the after party.

Ross did not dump Sanders after learning of his affair with the actress and is believed to be prepared to work to save their marriage for the sake of their children Skyla, seven, and five-year-old Tennyson.

"It's still too early to tell what will happen. She is talking to and seeing Rupert now for the kids, but as far as the marriage she's still processing everything that happened.

"No decisions have been made. It's been very hard on her dealing with this but she is very strong and keeping private about it," said a source.
