The period of the catechumenate in teh ancient church was no less than three years. Today, it is comparatively shorter especially since those who are received in are generally part of another Christian confession so that there are fewer stumbling blocks that would give greater challenges to those coming in from non-Christian confessions or who are atheists.
A friend of mine in the church was received in Pascha of 2008. But she decided that she needed two years before she was more or less certain. The priest agreed and this was done. Even I had doubts but my priest said that those should not impede me.
The fact is that none of us are ever completely ready. The church is not the goal, but the means. I've been long considering becoming a monastic though I have often remarked that my own sinfulness should keep me out to which an abbot told me that no monk ever entering a monastery was sinless when he came in. If only sinless people were to become monastics, then monasteries would be very empty places. Similarly with the church in general: If only those completely prepared were received then churches would largely be barren places on Sundays.
I know that you have a family to think about which also gives you greater pause. I was fortunate that I had no family to worry about on my journey and that I did not have to take into consideration their feelings, doubts, worries, etc. If it takes time, it takes time. Jaroslav Pelikan, the great Lutheran scholar, didn't become Orthodox until very late in life though he had been making strides in that direction for a long time. So, if you need time, take it. Otherwise, if the priest says you're ready, defer to his judgment since that is his to make.
At the same time, a little education never hurt anybody.
