Oh boy, I have so many, where do I start?

I quit a job and moved to another city where I did not want to be in the first place and she cheated on me shortly thereafter.

I moved to another country for another ex-girlfriend only to have her break up with me 5 months later.

I sacrificed my friends and cut off contact with them because she disliked them. Worst mistake ever.

So there have been several times.
