--Do you fall out of it fast and need an immediate break?
--Is it slow and gradual, sneaking up on you in time?
--How do you deal with it?
--Do you still try to work it out or are you just over it?
For me it was slow, it just kept coming up, each time a little firmer in my head. Then one day it hit me what it was.
I asked myself why I was unhappy. If I would be happier by myself.
The "work on question"
Well, it would depend on what was to "work on" most of the time there was nothing to "work" on and I just cut my losses.
But you can fall out and back in love with someone it jsut depends. If its that "spark" you are talking about you can get it back or at;east I have been able to . But It takes a lot of work on both ends and you have to aske yourslef if thats somting you want and if its worth it. Or you can cut your losses. For me most of the time I cut my losses.
