If you had to post here to seek clarification, you do not have the resolve for this kind of relationship. You will run into issues that you are not ready.
From my opinion I think a man should be financial independent, mature, and really got it together, in order to really get into that kind of relationship. Because in long term, you’ll be consider as a father figure to the child.
But if you just want date her for fun, please don’t waste her time. She has enough on her plate.
