Do you think that a on again off again relationship pattern can be solved?

Without getting too crazy with details, if you’re stuck in a pattern in which one party gets bored/“the itch” every few months, breaks up, and then regrets it a few days later, begs to be taken back, only to do it all over again…

How do you fix this pattern? Can it be done? Is it doomed? Would counselling help?

(three breakups in the course of two years, and are currently ‘on’)
