Do you have kids? I have joined a rec center in town and we do things together there, exercise, swim, etc... we ALL enjoy it and it is quality time togeter. You can do this by yourself as well....
I also joined facebook to see all of my high school friends (no one hitting on me etc.., nice) Just catching up...and seeing where / what everyone is in their life...
I have made new friends with the moms at school and the women at Al Anon and we talk on the phone, go to lunch, etc...
When I'm feeling alone I pick up the phone and call someone who understands, that is usually someone from Al anon, they are always happy to talk with me!!! It helps alot!
