I gotta tell you, this getting separated and breaking off a relationship after 30 years is a tough thing to do. People just don't know how hard it is, even if you are unhapy in your relationship, to make that step to make a change. I think that may be the toughest part--taking the first step--because we all think as the old saying goes: "the devil you know is better than the devil you don't". But after you take that first step off the cliff, you realize that now you can be responsible for your own happiness---and life will be for you what you make of it. It becomes sort of exciting. At times, you get almost giddy, and at others are scared to death, but all in all, so far I like the ride.
People have asked---are you lonely. My answer is: No. there is a difference between being alone and lonely. Being alone is a state of being---being lonely is a state of mind. A person can be alone and not lonely--or lonely but not alone. As long as you feel good about who you are, there is no reason to feel lonely.
There is another side to the story though, and that's the other person who was in the relationship with you. Sometimes they may have a hard time adjusting to the new challenges that are thrust upon them. They are in the same type of boat you are, but it isn't of their choosing so it is probably a lot scarier and lonlier for them.
Well---enough for now
