Understanding..

I just had my son on December 28, 2015.. I got pregnant in April of 2015. In July .. Of 2015 my bestfriend and her boyfriend came over to my house.. Well they also brought a guy who I had sex with in the past. ( we will call him D ) Witch I was like uhh.. Okay but next time ask. He was a cool guys so I was like sure. So we are all hanging out and they spend the night. Well around 5am .. Me and my bestfriend go in my room and I lay on my bed to sleep, and she lays on the trundal bed. I was awake by D who was behind me in my bed, grabbing my breast and playing with them..  I kindly ask him to stop.. Then he started playing with down there and I told him I was pregnant.. And he didn't care.. Then sex happened.. I was crying the whole time .. While he was choking me.. After everything was over.. I went to the bathroom and cried. My bestfriend came with and I explained what happened.. When I was leaving the bathroom D was leaving my house.. He gave me a hug and said hope your okay..
