If You've Been Cheated On Like Jen Aniston Has, Should You Know Better Than To Ever Be The Other Woman?

Not ‘cool’ Jen. How could you cause someone else the pain that you once went through?

Is Jennifer Aniston just as much of a man thief as her arch-nemesis Angelina Jolie? New reports indicate that she stole new BF Justin Theroux from his longtime girlfriend Heidi Bivens — which is exactly what Angie did back in 2005 by snagging Jen’s then-husband Brad Pitt. If the rumors are true, shame on you, Ms. Aniston!

Jen finally went public with her Wanderlust co-star at a MTV Movie Awards afterparty in early June, causing a public outcry when the world realized her virtually unknown new man already had a girlfriend.

“Heidi and Justin have been together for 14 years,” a rep for Bivens told the Page Six. “They met when she was 20 years old and he 24, and yes, she just moved out of their home last weekend. She has no comment.” Ouch!

A source close to Justin’s ex added, “Heidi is heartbroken. She was completely blindsided. She and Justin had been together for years, they had a home. Then he met Jennifer and everything changed. At first he claimed he and Jen were friends.”

However, a friend of Justin’s swears up and down that things were over between he and Heidi before his love affair with Jen heated up. Whatever the case, the time in between relationships definitely raises eyebrows.

When Angelina began dating Brad, her Mr. & Mrs. Smith co-star, immediately after he and Jen announced their divorce, eyebrows were also raised. Jen, who is notoriously reticent about sharing her feelings with the media, dubbed Angie’s move “not cool.” So how could she possibly do this to someone else?

When you’ve been cheated on, you’re at your lowest. You find it impossible to believe that someone you loved so much could betray you so badly.

I’m baffled that Jen, quite possibly the world’s most famously cheated-on spouse, could inflict this pain on someone else. Even if Justin and Heidi were over, the ink had barely dried on the death of their relationship. They should have waited before dating. She should have made sure it was really over.

Jen needs to remember that when a guy cheats — or when a guy who’s been dating the same woman for 14 years and that callously starts dating someone else the second he has a shot at upgrading — he’ll do it again. That old adage is relevant for a reason: Fool me once, shame on you. Fool me twice, shame on me. Jen, you’re being a fool.
