TS, a fetus/baby is not like a stain that you can wash away and forget about. Maybe *you* can forget about it eventually once you get tired of the girl and dump her like you plan to dump the baby, but seldom does it happen that the girl ever will forget. There's a chance that this will scar her for life.
There's a mandatory counselling before abortion is performed, perhaps you can join your girl in counselling and hopefully you will learn something.
