Tell me, what should I do? I Love a man much older than myself

I am now 26 years old, he is 48, met 4 years ago. He is married, but his wife does not live together, there is a common child of 10 years old, a girl. With my daughter, we have very good relations: sometimes it seems to me that she does not come to visit my father for a weekend, but to me. I feel the child reaching out to me.

There is a son yet, my peer, also in his relations with him all is well. But I want my baby, and I am perfectly aware of the whole burden of the situation. His daughter, his son, his former wife - he turns in all this and, apparently, I do not have a place in all this. However, he assures me that I am for him the best gift of fate after all.

The daughter was born prematurely, there are small deviations, so all attention to it. I understand that you need to make conclusions before it's too late, but how? Already so attached to a man, like this is yours, your own, but at the same time so far away. That's how to take and leave so far that no willpower, but live at this pace is not enough strength.

Maybe someone had a similar situation, tell me how to be?
