First, is natural for a boy to want to read his girlfriend's messages if possible (I'm not saying is right, just that curiosity is strong). But being jealous is another story. Being mad at you about a friend who wants to talk with you is ridiculous!
After all he should trust you more. I think he shouldn't be mad at you at all. But you should make him learn not to spy your facebook (even though, you could forgive him).
When your in a relationship, we all get jealous and upset or something that's small. If you guys have been together for that long, then you guys should have complete trust in each other. Also he has the right to read your messages I Think because then it would seem like your trying to hide something, but he also needs to understand that your friend lives far, and that it was many years ago.
Now your with him and that you love him. If he doesn't talk to other girls, then you shouldn't be talking to guys even if you don't like him. We all tend to get upset.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
