I know it's hard to hear this, but I'll say it anyway: The world does not owe you love, affection, intimacy, or a perfect partner. This is Earth, not a fine dining establishment, and you cannot just order up a dish and then be all bent out of shape when it doesn't just show up as you sit there, starving. We're all brown bagging it.
Since most of us cannot see beyond the immediate past and future, it takes a giant leap of faith to trust that fate is not against us. But if you at least be open to such an outlook, you'd find that your experience of disappointments drastically changes. You start feeling less victimized by circumstance and fear, and more inclined to follow the most constructive course of action.
Most women stay in unhappy marriages because of their children, even though as a whole they feel more empowered to support themselves and to create a new and better life. This would lead us to believe that there's an enormous amount of women out there who are living in an expired marriage, and this could very well include you.
