You should try talking about it with him. If he has more mature and loving feelings for you then maybe he should stop going out with his girlfriend BUT it all depends on what you agree on and if this is going to last because you don't want to get everyone all angry and upset if you two just break up a while later. And also if you and him have the right feelings for each other, when I said mature and loving I mean you may be looking for different kind of feelings but make sure you and him have them and it doesn't turn out to be a little fling.
Be mature about this: Talk to him and see how he feels. If he cheats on his current girlfriend, it only means he isn't mature enough to end his relationship, and that says a lot about his character.
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.
