Should i abort my baby or sleep with my boss to get a promotion?

Me and my gf are having financial troubles. I can not afford this baby at all and so it needs to be aborted. I asked my boss (whos really attractive) for a raise because i have a baby coming, but she said that if i satisfied her sexually then i would get a promotion. So the way i see it, should i cheat on my gf to get more money or should i abort the baby because cheating is bad?
