Good for you! My dad told me once that he resented having us because he didn't get to do what he wanted to and had to spend all this money raising us. Well EXCUSE ME! So it's my fault you don't know how a condom works?!

While I do think it's important to at least have a relationship with your parents, it sounds like it might be good to just go and be by yourself for a while. Give everyone time to calm down and think things through until it can be talked about like adults. Most parents would be thrilled to have a child that is so determined to go to school and have a good job and do what they love. If they can't handle it, it's their own insecurities. Congratulations on standing up for yourself!
