can my son's father pay his lawyer to take him away from me if i dont have a job but my parents help me out?

No one can simply "take away" your child without court intervention, legally.  It sounds as if there is an initial temporary restraining order to be issued, attached with a lawsuit for modification or an original Suit Affecting Parent-child Relationship.  In this case, you would generally be notified, provided the father has your location information, and have the opportunity to present a case as to why the father should NOT have the ability to take the child.  He would also first have to present his case to a judge at least in the form of an affidavit before having this right to "take away" your child.  There's more to it than this, but the short answer is NO.
