Hi I want to know about my future. I want to know when I will marry and how many children I will have

No one can know that.

Sounds like a thread for the psychic section.

My crystal ball ran out of batteries.

Nobody can answer this for you. Anything would be a guess. Same for this question you posted which is nearly identical:
