@janbb is telling you the straight truth. Don’t take out your frustrations on her.
You came here for advice. That’s what we give here, advice, based on exactly what you tell us your situation is.
You are 18 now, so that makes you an adult. You’ve got adult problems right now. First things first. Unless this guy physically abused you, he really hasn’t done much more than be a jerky boyfriend (like so many other jerky guys have done to naive females over millenia).
Right now, it’s time for you to grow up. You have no choice at this point.
Your best bet, whether you like it or not, is to come clean with your parents. If they won’t pay for your college because you were “naughty” then that’s the breaks, kiddo. Although you were underage, you knew what the consequences of sneaking around, and having underage sex, and hiding this from your parents would be, but you did it anyway.
What you didn’t plan on was STD. But now that you have one, be grateful that it is curable if you deal with it now.
If you think this dude is guilty of statutory rape, which it sounds like he was, then it’s best for you to tell your parents, and report him, and suffer the consequences of their not paying for your school.
You need to educate yourself on how to protect yourself from this point forward, against rape, against other worse STD’s, and pregnancy.
We are here to tell you where to get help. Don’t blame the messenger. You are an adult now, and you have to take responsibilty for yourself, including your part in getting involved with this guy.
If you want to go to the police, get all your proof together and do that. But you don’t have to do that alone.
If you decide not to go to the police, then you just need to get your own act together, and find better ways to live your life, to avoid the pitfalls you’ve already experienced.
I can’t say enough about Planned Parenthood. They are not just dispensers of birth control. They can help you create a better plan for living a healthy life. Talk to them, and let them know that you’ve been through. This is in addition to getting treated for the STD.
I am not a parent, but I have been the advocate for several friends who have experienced unplanned pregnancies, an abortion, and being catfished. Every female I know has been hurt, in small ways, and big ways by males who either lied to them, cheated on them, abused them, or simply did not care about them.
I wish I could grab every young woman and shake some sense into them. You have to be independent. You have to take care of yourself. Even if you are lucky enough to share the love of a good man. You have to be your own advocate.
We are here to help, but you also have to help yourself.
