Economy and Relationships

I have spent many years, 13 to be exact, with one man and now I am feeling that I should have moved on a long time ago. After his years of lies... the last one was the last straw for me, but now I am stuck because I have recently lost my job and can not afford to pay the mortgage on my own. Each day is a struggle to keep up with the image of looking happy when inside I am scared and desiring an escape. There are probably many people in the same boat and it's a lonely feeling. Now that I am older I have a better understanding of what kind of man and life I want. I missed opportunities along the way and as a result many of those opportunities are now married with their own children. I am not one to cheat, so now my only option is to make enough money to break free from my internal jail. It is so difficult to make connections with people as you get older. They have their own family and friends that they have had for years and are very reluctant to let you into their inner circle. My "inner circle" is so busy with their own lives that I rarely hear from them as well. Just wondering if there is other people out there who feel the same way??
