The actress who has a three-year-old daughter, Suri, with the Hollywood superstar is reportedly growing increasingly frustrated with the couple’s hectic schedule and is keen to spend more intimate time with Tom.A source told Britain’s Closer magazine: “Katie has become noticeably more miserable in the last few months. She finds it incredibly taxing to lead a life that revolves around Tom but that doesn’t include enough intimate time with him to be genuinely fulfilling.“She doesn’t just want to go to red-carpet events with him. She always feels like she’s competing for Tom’s attention.”Friends are reportedly worried about the former Dawson’s Creek star, who is said to be becoming isolated from her Los Angeles social circle.The source added: “Everyone is worried that she’s close to breaking point. Katie spends most days alone looking after Suri. She’s a devoted mother, but it’s a lonely job. She and Tom have such separate lives.”
