I usually agree with Dawn , but in this case I am going to say the opposite.
If he has not done anything to make you worry about in 8 years, why are you worried now? Do you have some secrets you do not share? I think what you put out there is what you get back.
If you are honest and trusting in your relationship you will get that back from your boyfriend.
If you are secretive and and jealous, he is going to respond to you in a secretive way to avoid your behaviors.
He has told you the answer. Why SHOULD he tell you? You will just get upset? Why are you surprised that he continues to hide it from you? Because you make him feel like you will always think the worst of him..
It is a shame he has to live this way. It is easier to trust the other person enough that you would not have a reason to look for secrets.
I am not jealous of my husband and his friends, old girls friend old lovers, because he is with me, he married me and he tells me he loves me and I believe him.. FYI, he does have a a lot of old girlfriends on his facebook and some of then asked to be my friend and I accepted.. No big deal..
Some people seem to look for drama, even if they do not realize they are the drama.Do not become one of these people..
Go to therapy and work out your insecurities, especially if "This is typical behavior that I have encountered in the past. So, I am hesitant to bring it up even casually.This is typical behavior that I have encountered in the past. So, I am hesitant to bring it up even casually" This is not a totally healthy relationship. .
