Do you think people write others off too easily and label them as 'psycho' when it comes to relationships?

I think a lot of people (especially men) write off their failed relationships to the other person being "psycho" because, 1. it's a very hurtful thing to say to someone and 2. it takes all the responsibility for the relationship not working out off of them. Someone who truly loves you will try to work out relationship problems if they won't they're not worth your time or effort.
