You might give love to non-romantic partners. Perhaps older family members. Maybe volunteering to look after unwanted pets at your local animal shelter, or volunteering for special needs children. There is a long list of people and animals who would thrive if you gave them your affection.
Being a happy single is far, far better than being in a bad relationship. Too often, women who fear being single stick with a totally unsuitable partner who makes them miserable. You know that it's not all candlelight and roses. Currently half of all American first marriages end in divorce; with a higher rate for subsequent marriages.
Sometimes when people feel desperate for love, they project too much need onto other people. In contrast, women who seem happy in their own skins, as they are, project a kind of self-confidence that others find attractive.
So please get just how wonderful you are as a single woman.
