My dream of marrying?

My ideal partner is a one who really loves me. But, I am so selfish. I know the truth.
In fact, I don’t want have my wife. In other words, My ideal partner is ghost. If I meet ideal partner, perhaps, my mind can’t be changed. However, Although I don’t want to marry someone, I want to have son or daughter. I want to have my children ,two or three. Without marrying someone, is there way to get my children?
