Margot Robbie says one should learn from his or her previous relationships because that always makes the person stronger. The Suicide Squad star opened up about her relationship with her boyfriend Tom Ackerley and said they share a great bond because of their openness to each other, reported Female First. “Over the years, you experience enough situations and your share of heartbreak that you tend to build up defensive walls. That happens to most people. The trick is to be able to learn from your previous relationships and become stronger, so that you can allow yourself to be more open and vulnerable again,” Robbie said. Recently the actor said that Britain’s Prince Harry is quick on texting, unlike herself. When it comes to texting, Robbie said: “He is pretty quick on text, actually. Unlike me. I write back four days later, weeks later sometimes.”
