There is a 91.86% match between your horoscopes.
However I must add that both have a poor horoscope with less than a net 40% strength and particularly your 1st,3rd, 4th and 5th houses are not potent enough. What these houses represent you can read in my article ‘Astrology – A new Version’ on this web site or on http://www.navagrahastro.blogspot.in/.
The boy has a net residential strength for planets of 25.20%

To your question, whether you should marry him, there is a very good match of your horoscopes though both with poor net strengths. You will get along well together through thick and thin.
