Let this be a lesson
I'm on here once a week preaching why guys should take EVERY and ANY measure to make sure that a woman doesn't get pregnant.
There is a TON of women running around the USA that realize they can make a fortune being stay at home moms, much more than they could make trying to work. It is to their benefit to get pregnant by as many working males as possible. The world is a brutal place. The woman who would do anything for you one day will be doing anything to drain your bank account post breakup.
Let this be a lesson to all the young guys reading this post. Don't take these kinds of risks. Most likely his gf was pregnant by another guy and he had nothing to worry about. However, you should never, ever take that chance. Always pay for the abortion just in case you should happen to be the legitimate father. Nevr sign anything until DNA has been done. DNA can be done while she is still pregnant by Amniosetisis (not sure of the spelling).
Go with her the day of the abortion. Even if you have to quit your job, miss an exam, this is one of those you want to make sure gets done. Paying child support will ruin the rest of your life. You can't afford nice clothes, vacations, nice ride, etc while paying child support.
Go with her.
After it's over, look her straight in eye and tell her it's over and she needs to leave you alone. She sounds like a psycho. Send her back to the poor house she crawled out from under. Call the police if she ever shows up at your place again. Never speak to her ever again for any reason.
She has caused you enough grief. Put this to rest for your own sake, please!
