Jessica Simpson knows a thing or two about falling in and out of love in the public eye. Perhaps that's why when she spoke to Glamour magazine about her relationship with Dallas Cowboys quarterback Tony Romo she was willing to speculate that if the pair had broken up by the time the issue came out, "he'd still be a huge part of who I am today." Simpson and Romo broke up last month.

"If this article comes out and we're not together, I'd still love him, and he'd still be a huge part of who I am today," Simpson says in the September issue of Glamour, adding that breakups feel like "a death in the family."

Simpson, who divorced Nick Lachey in 2006, added that she wasn't sure she'd marry again after the divorce. She said, "It was hard to imagine I would ever walk down the aisle again."

She then described what it feels like for her to end a relationship. "You go through the mourning stage, then the rebellion, and then all of a sudden you have to find life by yourself," said Simpson, who has also dated John Mayer. "Once you do that, you feel complete — and that's the only time you can truly fall in love again and give yourself over completely to another person."

Despite all the public scrutiny around her life, the 29-year-old admits that "I don't regret anything I've gone through." She added, "I don't know what the future holds, but I hope that my life as it is now doesn't change. I'm very happy and comfortable — it's a great place to be in."
