In preparation for marriage, a key aspect is maturity on both the lady and the man’s paths. By maturity, I don’t just mean in age but also in spirituality, emotional stability, physical growth and strength, etc.
Marry someone who will take responsibility for his/her actions and not look for someone else to blame. Also, don’t get married to someone whose parents still dictate his every move. If your parents are still dictating life to you, then you are not qualified to parent anyone and are therefore not matured enough for marriage.
Again, if you are not mature enough to be a parent, then you are not mature enough for marriage. A man ready for marriage should be able to ensure the welfare of his spouse and children.
