Hey there,
first of all, do not let anyone - friends, parents, your boyfriend - presuure you into making a certain decision. This is something you have to put a lot of thought into. I would advise against abortion, only because it is very emotionally damaging to lose a child, especially if you choose to do so intentionally. Your parents are right to tell you it is your responsibility, because that is what it is. Your baby, your child, your job to look after it. If you feel that your boyriend will not be there for you if you decide to keep the baby, don't let that decide your baby's fate. If he's not man enough to support a decision you're making about YOUR body, than he's not worth losing your baby over. If you honestly feel that you can't look after a baby, then give adoption some serious thought. There are lots of options with that aswell. If you can't stand the thought of giving up your baby entirely, look at couples willing to negotiate an open adoption. That allows you to be in your child's life, but still lets your child be in a financially stable home. Abortion is not the only option, and many people have found ways to be a single teen parent and give thier children the best life. There are lots of support groupd out there, and people willing and ready to help you through your pregnancy and looking after your baby while trying to get school, work etc. done. This is something you really need to think long and hard about. To be brutally honest, your boyfriend is being selfish by pressuring you the way he is. Having an abortion will haunt you mentally and emotionally for a long time, and it can cause a lot of psychological issues if you're pressured into it, or are not fully commited to it. It is also can be physically taxing. I wish you all the luck in the world, but I ask you to please consider all the options and think it through on your own. Don't let someone else bully you into something you don't want.
