I've only experienced it as described in the article, with a person as the limerent object. The limerent state is sustained by uncertainty, the small and tantalizing chance it could work out the way you want and the undeniable chance it could fail. One way out of the situation is to make success impossible (say, by a breakup) and therefore reach certainty of the outcome. This is of course the last thing most people would do, but to end what feels like permanent madness, you take that deal.

I think if this article really described you, you would stop dead in your tracks reading it. There is what the general public casually calls OCD and intrusive thoughts, and then there are many horrifying flavors of the real deal.
