I went through this eight months ago and it is honestly the most difficult thing that ever happened to me. Eight months on and I still think about it every day and what could have been. But, for me, it was absolutely the right decision. My boyfriend and I are just not ready for children and it doesn't sound like you are either. One day you will be and you will give your child the best life you possibly can but if you're not in a position to do that now, then you should not continue with this pregnancy. I sympathise, I really do. I didn't want a child but I didn't want to go through the procedure either. I tortured myself for weeks and let myself believe what I was doing was wrong and cruel and that I was a terrible person but when it was all over, I felt nothing but relief and I knew I had made the right decision for me. And you have to make the right decision for you. Maybe your decision won't be the same as mine, maybe it will. But do not let your boyfriend make this decision for you and don't make this decision for him to keep him happy. You have to think about yourself now, and whether you are ready to bring a child into the world.
As I say, I still think about what happened very day. If I had continued with the pregnancy, I would have a new born baby right about now. But I also wouldn't be able to have gone back to university (I returned this September gone after a 3 year break) and I probably never would have. I don't regret my decision, but then I always knew deep down I wasn't ready. What is that voice deep down telling you to do? Listen to it. Best of luck. And if you need to talk to someone who's been there, feel free.
