The world No 3, who in 2013 became the first Briton to win the men???s singles crown since 1936, married long-term partner Kim Sears earlier this year as he continued to return to form following an injury-ravaged end to 2014.
Murray, now 28, is in fine form after winning his fourth Queen???s Club trophy and believes his stable relationship has aided his rise back up the rankings.
???I hope all the recent tournaments and practice will have a bearing ??? that???s the point in playing all the tournaments outside the majors,??? said Murray, speaking at the launch of his new Under Armour Wimbledon kit.
???It helps to build up confidence; to try to win matches against top players, learn about the things you are doing well and then when I???m in the practice week ahead of Wimbledon I???m focused on what I need to do.
???Being in a stable relationship in your personal life also helps. Obviously people don???t see that on the cameras but if everything???s good then you aren???t having so many emotional ups and downs distracting you, and you???re not worrying about what???s happening back home.???
Murray has been seeded third for Wimbledon, which begins on June 29, with world No 1 and defending champion Novak Djokovic topping the men’s seeds from seven-time victor Roger Federer.
It means Murray, who was knocked out at the quarter-final stage last year, could face either Djokovic or Federer in the semi-finals should they progress.
