I agree with the other 2 posters. I assume you are young, because when people are older they usually have longer histories but that is all part of growing up.
When you meet the right person only the present is important.
Actually I am more concerned about your life now with him, is he jealous in general. Do you go out with your friends and is he ok with that or does he question you when you come home.
Don't tell him more than what he wants to hear but make sure that your life with him is what you want for your future.
