Yes to this... ^ Life is a lot easier with a partner. Single life for women is often celebrated on here, and some posters act like they're Bridget Jones or something, with a shiny apartment in London, a 6 figure a year career, lots of men fawning over them, a great social life, and a big circle of friends.
In reality, for many single women, life is difficult. A constant financial struggle, lonely evenings and nights in their home, no-one to share their everyday troubles and worries with, no-one to do hobbies with, no-one go on a day trip or holiday with (or out for meals, or to the cinema with.) And no-one to look after them when they're ill. Not every single woman has lots of friends, some have none, some have a couple of friends, but not really anyone they can fully rely on/depend on when the chips are down, and they really need support.
It's even harder for women with children. I have seen plenty of women (who are divorced/single/never married,) who have children/teenagers/young adult children who are NEETS, scrapping with others at work to get any additional hours they can get at work, for the extra money, purely to make ends meet. They are often on the bones of their arse. Kids are 18+ in some cases, and bringing no income in, and the father doesn't contribute because the children are legally adults.
Unless it's an abusive/toxic relationship, it's understandable why many women stay in relationships/marriages, even if they're a bit bored, and don't really love their partner. It's just a fact that in the vast majority of cases, that life is easier if you're in a couple/living together.
