I agree that the first thing is to find out if you are actually pregnant.

Next, whether or not you are, your boyfriend has no right to demand that you end your pregnancy (whether or not he knows about it). Both of you took a risk, and the consequences are real, for both of you and for the potential baby. If he didn't want to have to face the possibility, then he should not have had sex with you. Let me guess, you probably didn't use birth control because you don't believe in it either? And that's probably why he told you to just not tell him and get an abortion? Maybe he wanted to use birth control? Okay, but then you have to take a serious look at your beliefs and values. Is using birth control worse than having an abortion? I don't want to be mean. I really do feel for you. I just want you to think about what you do from here. Are you willing to take that risk again, knowing the consequences?

From here, you will just have to decide what you can best live with. If you are pregnant, you will never forget what you do about it. If you have an abortion, will you be able to live with that for the rest of your life? If you have the baby and either give the baby for adoption or raise the baby, what impact will that have on your life? Between all of the options, what will you feel best about a year or five or ten down the road? At the end of your life, what would you like to say that you did?

Please also consider this relationship. Where is it going, and how does it fit with your plans for the rest of your life? How do your values and your boyfriend's values compare? Are the differences reconcilable? I just have big concerns about someone who would put such a huge burden on you so that he can avoid even the responsibility of knowing about it, or the inconvenience of having a pregnant girlfriend.

It is your decision, but you did ask for help. I hope that I was not too blunt, but I just had to call it as I see it. And none of my questions are rhetorical. You decide what the answers are for you, because it really all comes down to what really matters to you, and what you are going to do with your life.
