I would agree with others, that you might consider taking a few months away from everything, and staying in a monastery to see if that lifestyle appeals to you, or not. Best to try it before tying the knot rather than after, right?
Bringing up children is both challenging, and rewarding, but I must inform you that, the affection one has for one's children can weigh on one's mind, especially when they go through pain or distress themselves, or occasionally inflict distress on their parents. Personally, if I know that my kids are in distress, I cannot get my mind to calm properly. (They live mostly at their mother's house, and I cannot control what happens over there, obviously). There is a tie of affection that links their welfare to mine. In short: you might find that some aspects of the Path, such as jhana, are very difficult for persons in family life.
Then the Blessed One, picking up a tiny bit of dust with the tip of his fingernail, said to the monk, "There isn't even this much form...feeling...
perception...fabrications...consciousness that is constant, lasting, eternal, not subject to change, that will stay just as it is as long as eternity."
