We have had our fair share of challenges like every marriage does," she told her followers. "I think that when you're with someone for a long time... everyone goes through things. You bring different traumas into your relationship."Despite those "hard seasons," Heather Rae credited the strength of their marriage to Tarek’s consistent romantic gestures, which she says began the moment they met. She recalled how he "moved mountains" just to secure a first date with her, despite his grueling filming schedule and parenting responsibilities at the time.CLICK HERE TO SIGN UP FOR THE ENTERTAINMENT NEWSLETTERHeather Rae detailed that early romance, explaining how Tarek managed to surprise her at every turn.
