For many years male children were brought up with 'boys don't cry' which is no longer so. A real man will cry when he has need too and there is nothing weak about a man crying. Men are not quite as emotional as women (they don't have the vast hormonal changes like women) but, many more men are feeling free enough to cry if they want too. Crying gives one relief of tension in the body and is a natural function for humans. It is obvious your boyfriend still loves you and you have broken his heart. You already know why he is crying over the break up so cut this poor young man some slack and either stay with him and try to make the relationship work or, move on and do not bother him any longer.
