The survey was carried out at the Lakeside Shopping Centre in Essex.
Lakeside spokesman Sophie Scott said: "These results will strike a chord with millions of married women all over the UK. After a busy week at work, we all crave escapism and some 'me time', and it is clear women prefer to spend theirs with girlfriends than partners."
The study revealed a third of women agreed that they prefer to spend a day off with a friend because they were more fun and more likely to enjoy talking about relationships or gossiping.
Shopping, going to a spa or having a meal and a glass of wine topped the list of activities women enjoyed doing in their spare time.
The survey revealed two thirds of women felt guilty as they did not catch up with their friends often enough.
