text: difference when marrying a 23 year old girl in 30 year od woman? i am 23 year old but my boyfirend is 56 year old, he said that if i was only 30 plus of age surely he will marry me. i don't know what's the difference if am 30 plus year old or 23 year old he is trying to tell you that you are too young for him, and the age difference will interfere with your marriage in later years. i am 58 and i would not even think about marrying a lady under the age of 40. you did not mention if he had any kids of your age or older.  i am sure there are several reasons that he knows better to marry someone of your age, and really i do not think that you would want to marry someone of that age either. you may think that you love him, but do you love him for his money? good luck
