Of course there is.
See people like to suppress their feelings of guilt then they like to take that guilt out on the one's they feel guilty towards.
Well quite frankly it's a defense mechanism. They don't want to feel guilty anymore. They begin to nit pick and just become real UN-freaking-pleasant to be around. Just so that they can calm their feelings of guilt and reassure themselves that what they did, have done, or are thinking of doing isn't as bad as their conscious is making it out to be. Surely their actions were justified because you did XYZ.
For instance: You've been in a relationship with someone for a long time. Suddenly they seem to be a jerk. They are biting your head off or just make your life miserable by nit picking at everything you do. Even if it's the same stuff you've done in the past. But yet they seem annoyed by it?
It's guilt. 100%.
So if someone's attitude has done a 180 - that's enough reason to believe there's feelings of guilt behind the switch-a-roo.
Talk it out. Or let it go. Either way don't let it affect you as a person.
It's them. Not you.
