unwanted pregnancy

I was sexually asautled and now im 16 years old carrying twins. im 6 weeks along and just found out im having twins. it hasnt been the easiest i must say balancing school and work is a struggle already and my twins arent even here. I told my boyfriend about expecting twins and his words were "Thats your stupid mistake not mine I would of pulled out. Im keeping it one hundred with you im not fake." I have to admit that was hard because it wasnt my fault this happened to me, and he treats me like it is. I dont want to abort them and im not sure if i can handle more stress i already have a few grey hairs from stress and dont sleep. Is adoption a good way to go?
