Confusing

Can someone help me understand the mentality here. A lot of girls on this this website claim to want a relationship but quite a few literally force you to carry the conversation. What I mean by that is you are expected to generate all the conversation and questions, that is understandable for the first few messages but quickly starts to become irritating and condescending especially when you have been communicating for a week or more. Where I was raised it generally means the girl wants you to go away as quickly as possible. A relationship generally means two communications or am I missing something here?
