My sport is basketball, and I've never known anyone who wants to play with a ball hog... and ball hogs rarely realize they are part of the problem working against the team.
My advice... go back to fundamentals.
Start with dating again... get to know the "new" people you are. Be intentional. Relationships are not about keeping score between team members. They are about each member giving it their best effort. Sometimes we loose. Sometimes we have a slump. Winning teams are made up of members that make their teammates shine.
