So, my ex-girlfriend got pregnant and moved back to california (i'm stationed in virginia, and we were together here). i found out that she had cheated on me "once" but she was still confident that it was my child. needless to say, i ended it with her, but i still flew out to california for an ultrasound and post birth (i was providing japanese disaster relief at the date of birth).

he looked exactly like me. or so i thought. i took a paternity test anyway and it came back negative. i'm not the father. however, this is not a legally binding paternity test. i payed $350 for a "peace of mind" test. evidently its the same test, minus the strict chain of custody requirements.

i'm still worried this girl is going to try to screw me. any advice?
