I used to mistake boredom for loneliness, but no longer. It was odd that whenever I was bored I would go to the bar, talk to some people and sure the boredom would be gone for as long as I was there. However as I returned home the boredom would return which is why I mistook it for loneliness.

One day I got a hobby to work on and I upgraded my cable TV and poof I was no longer "lonely". I started thinking about this and I finally realized that I did not want to be around any people. This was a number of years ago and today I am somewhat of a hermit, talking to nobody but my wife, whom I met in a rehab centre.

In the last 12 years I have not felt lonely even once, even if my wife has gone away somewhere. If were to split up I'm sure I would talk to nobody except my doctors.

Yikes, I typed all that and realized I had not addressed the OP. In short I firmly believe the only person that can end your loneliness is yourself. Either by learning to be alone and enjoy it or by continually searching for a BFF/spouse. There is someone out there for everyone!
