Yes tell him because he left the DVD at your house. He probably didn't think anything of it, or should have been more careful, I'd hate my boyfriend leaving a DVD of him and his ex at my place.
Leaving the dvd at your house might have been accidental but it was obviously too tempting not to watch and as they were not doing anyting too embarrassing it might be worth discussing - good luck whatever you choose to do.
YEs he wil not worry and you can work out all your emotions torward eachother! :).
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.
