Moving on and being okay

I just turned 15 when my boyfriend at the time sexually assaulted me. I said no and he ripped me by the hair and forced me to give him oral sex. It took me a long time to break up with him, and a even longer time to come forward to my family about what happened. I'm 17 now, and for the most part I'm okay. But I have a very hard time maintaining relationships. I'm very untrusting and often get to scared I'm going to be hurt. I guess the point of this post was to ask if anyone who's been through something similar.... does it ever get easier? It's been almost 2 years. Will I ever be okay?
