Sure. Assuming you desire a long term romantic relationship, if you end all romantic relationships that you see as most likely insufficiently desirable for a long term relationship there is a good chance you will not develop a good enough grasp of relationship etiquette, skills, & problem solving to appease a candidate that they would deem as a sufficiently desirable long term romantic companion. That behavior wouldn't strictly prevent the person from finding someone who would put up with their lack of knowledge but it sure would have a non-negligible probability of doing so.
