1. Relationships include a lot of sacrifice, compromises, and love. It is often overlooked that there are inevitably rough periods within a relationship, we must be willing and also ready to contribute whatever percent is needed to make it to 100. I personally have some friends in relationships that can't seem to grasp this topic and it often leads to the relationship ending, have you had experience with something similar to this?

2. I think the cost-benefit analysis is a reason that creates issues in relationships because is can go hand in hand with the idea of partners being selfish in relationships. I find myself being the opposite of cost-benefit idea because I always do things out of love that I want with no expectation of anything in return. Thoughts?
