I'm in the process of getting divorce after 8 years of marriage. Yes it is very painful. When I first moved out I was very very lonely. I have allot of hobbies (karate, gym, mountain biking, Harley) but still at night it gets very lonely. I'm just now starting to adjust to it and I'm starting to be happy again. People told me not to get into a relationship right away. I almost did and I'm sorta glad it didn't work out. I know now that it would have been a very bad thing. I need to get my head on straight and pay attention to myself before I can pay attention to someone else.
Staying busy really helps. I've been hitting the gym 2 nights a week and karate 2 night a week. So that keeps me pretty busy. Sitting around thinking about everything that happened just bring you down more.
I hope everything works out for you and remember that we are always here to talk to.
