While each of these relationships was fun, some were more successful than others. Success in relationships on The Big Bang Theory it wasn’t just how long the couple had been together or even if they were married. It extended to other things like how much they loved and supported each other through good or bad like illness and the death of a loved one.

9 Howard & Bernadette


Their love story didn’t get the same attention as Leonard and Sheldon’s, but Howard and Bernadette’s relationship on TBBT was the most realistic. After a tentative debut in Season 3’s “The Creepy Candy Coating Corollary”, their relationship grew more serious until they finally married and later had two children.

When it comes to successful relationships, Howard and Bernadette ticked a lot of boxes. She called him out on his scary behavior and he grew up on it a lot. They supported each other during Howard’s vasectomy and Bernadette was in bed rest during her second pregnancy. When he lost his mother, she helped him out. Having weathered so many storms together without going their separate ways, there is no doubt that they are the most successful couple.

8 Sheldon and Amy

Despite the slow start, Sheldon and Amy stood the test of time, and by season 12 they were married and had a Nobel Prize to their name.

Amy has changed dramatically during her relationship with Sheldon and him too. She was happier, with more people who really cared about her, and he was more considerate. For example, when Pemberton and Campbell suggested removing Amy to improve their chances of winning the Nobel Prize, he refused to do so, even though it was something he had always wanted. Although Sheldon shows off those growing moments that highlight their success as a couple, he often felt like Amy was his babysitter and not someone he had a romantic relationship with.and he treated her that way too.
