<human>: Can you condense the text into three sentences or less?

My boyfriend and I have been living together for about 9 months now and we've always been very honest with each other. He always said that he didn't want kids (never had but stood by his then-gf when daughter was born) but knew that one day i probably would.

Throughout our relationship he has dropped hints that maybe he wasn't dead-set on that opinion. We talked about it again yesterday and I can see that the only reason we would end up having a kid is if it was that or I leave. (Not that this is a demand I'd ever make but from his point of view). He has clearly said things- completely unsolicited- that he thinks I want to hear because, good man that he is, he wants to give me what I want.

He has a teenage daughter who has learning difficulties and the mental age of a seven year old- we bonded quickly but I know at this point I can never be more than a friend to her. We only have her every-other weekend as she lives in another city. I never thought I'd have to make a decision about kids so early on in life- it's something I thought would happen just because, yknow, that's what people do.  Never thought more in to it than that. 

I don't even know if I will want kids, but have a feeling I will. He has always assumed that I will eventually. Do I cut loose now from a family I love? Or do I stay, hope it never becomes a problem and reassess later. Or else, stay and maybe miss out on a huge part of life that I want to be with them.
<bot>: boyfriend has a daughter, I love them both but think I may want my own kids one day. Stay or go?
