50/50 In A Relationship...Is That Possible??

I think a 50/50 relattionship is all mental. I fyou guys are on the same level mentally and you guys are real with each other, then you can have a 50/50 relationship. Otherwise one person is simply playing with the other. What exactly do you mean 50/50 though? Do you mean who makes all the decisions in the relationship, or do you mean who cares about who more (dont know if i said that right or not)
