Pippa Middleton was desperate to have her ex-boyfriend "put a ring on it," but apparently he couldn't find one. There's a new report that says the British socialite is now feeling "lonely" after breaking up with her long-term love Nico Jackson and also incredibly disappointed that she won't be walking down the aisle anytime soon, as she was hoping to have a star-studded wedding, just like her famous sister.

To make matters even worse though, insiders are saying that Pippa is feeling down in the dumps as she has been struggling to escape from her sister Kate Middleton's shadow in the celebrity spotlight as well.

According to the Daily Mail on Sunday, things are going from bad to worse for Pippa, as she was spotted looking both heartbroken and sullen while she was out and about in London this past weekend.

A source close to Pippa dished, "Friends say that when she suggested a break-up to Nico, Pippa had suspected he might react with a grand gesture to win her back - like a marriage proposal..."

The insider added, "Instead, Nico surprised her by accepting all too swiftly that the relationship had indeed 'run its course' and walked away, flying back to the Geneva flat he has called home for almost two years. Pippa was left behind, broken-hearted."

Just recently, Pippa was spotted spending one-on-one time with her ex-boyfriend in London, while hoping to make Nico jealous, but unfortunately the plan didn't work in her favor.

Pippa and Nico were on-again, off-again for nearly three years. Many friends in their inner circle say distance was a huge problem in their relationship, as Pippa lives full-time in London while Nico worked as a stockbroker in Geneva, Switzerland.
