I was going to say about what Kittyzee said... From what you posted, it's not the huge house and fine living that you want, but the companionship, community, children, a sense of belonging, of being needed and important, etc.
Often, you find the best people when you're not looking.....
Meaning, being involved in other things, having a full life, and being happy and content will give meaning to your life, and when you are content, it seems that good things (like good men) come to you, rather than you having to search them out.
Volunteering needn't mean a soup kitchen. There are all sorts of ways to get involved helping people, and meeting people. Thrift stores run by charities often operate with volunteer labor, animal shelters need volunteers, kid's after school programs, people that tend to pets while the owners are in the hopsital, and also clubs you can join, like gardening clubs, ecology groups, any special interest you may have - bridge, cooking, auto repair.
MeetUp.com is a great way to get to know people with similar interests. NOT a dating group at all, but people who share interests. Find the local chapter in your area. I belong to a wine-tasting MeetUp, two or three cooking ones, and one that visits museums.
