Hmm, this is a complicated matter. If isn't rape when you gave in (oral and stuff), but that half-penetration bit could be if he forced himself on you like you seem to describe. This obviously seems very difficult to you, so maybe you should cut ties for a while.
Wounds take time to heal, if they ever. He's ok now, but how long before he acts up again? It's very hard for me to give you a complete answer, as it is complex and I know very little.
You should probably try to forget him, since that image of him forcing himself on you will probably never disappear as long as you stay with him... Best of luck.
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.
