WHATS THE BEST THING FOR A SINGLE MOM TO DO?

HI I'M SAMMY AND I'M A SINGLE MOTHER. EVERYONE AND MY BABY FATHER KEEP TELLING ME LET MY BABY FATHER TAKE A DNA AND TAKE HIM TO COURT. I'M JUST NOT FEELING RIGHT ABOUT THE SITUATION BECAUSE I LOVE MY SON AND I DON'T TRUST HIM TO BE A GOOD FATHER. WHAT SHOULD I DO? WHAT U THINK IS BEST FOR ME AND MY SON?
