Reese Witherspoon and ex-husband Ryan Phillippe could have stumbled across each other this past weekend, reports RadarOnline. Witherspoon, who was married to talent agent Jim Toth on Saturday, had her wedding at her Ojai, California home.  Phillippe and new girlfriend Amanda Seyfried were vacationing at the expensive San Ysidro Ranch near Santa Barbara, a mere 30 minutes from Witherspoon’s home.  Phillippe and Witherspoon share two children together: Ava, 11, and Deacon, 7.  The two finalized their divorce in 2007.

What are ways to tell that your ex is jealous of your new relationship?

Cupid’s Advice:

Even when all seems to be said and done in an ended relationship, it’s possible for leftover feelings to resurface. Here are a few ways to find out if your ex is jealous:

1. He wants to see you: Even if the two of you agreed to be friends after your relationship ended, there’s still a line between being friendly and clingy.  If your ex contacts you more often now that you’re in a new relationship, it may mean that he’s jealous.

2. Ask mutual friends: If you share mutual friends, ask your friends if your ex has been mentioning you more than usual lately, or if your ex seems to be moody.  A bad attitude and a need to bring you into the conversation is a sure way to tell if your ex is jealous.

3. His dating tendencies: If it seems that your ex is taking a long time to move on from your relationship, it may mean that he still has feelings for you.  While your ex just may not be the type to rush into a new relationship, his repeated avoidance of the dating scene may be cause for concern.
