Do you have any hobbies that allow you to get out of the house? For example, I am into photography and I often go out by myself to different places to take pictures. I am always meeting interesting people. A lot of times it just takes a little bit of bravery to talk to them, but having photography in common helps. A lot of times if I meet someone taking pictures at the same spot I am, I will ask them about their equipment and their technique, and they are always more than willing to talk about it and ask me about mine.
There is a website called
www.meetup.com It is a great resource for finding like minded people in your area. I am a member of an organic food and farming club, as well as some photography clubs. I don't go to many meets, but it is nice to know that it is available if I ever wanted to get out of the house. If you just type in an interest, a whole range of clubs will come up in your area. There are also groups that just get together to play games, watch movies, or eat out at a restaurant.
Are your kids involved in any clubs? 4-H is a great opportunity for them, and a great opportunity for you to meet other parents with similar interests. I run a club with my mom and a lot of the parents are very involved, and several of the women have made friends with each other. There are tons of other clubs out there for kids (scouts, etc) but I grew up doing 4-H and I never hesitate to recommend it to others.
Do you have a library in your area? Book clubs are great especially if you like reading. Also, craft stores often have craft events. I've gone to these with my mom a few times and we always meet other ladies who love to talk and get together. Look in your local newspaper for event listings. Now that your husband may be home more, take advantage of free concerts in your areas. Heck, sometimes there are even really cool festivals! Even farmers markets are great. I go there a lot by myself and will chat with the vendors. They are always very friendly.
