How should I feel?

I'm lucky enough to have an awesome man in my life. He's been my everything since my son was 3 months. My child's father denied my son since he found out I was pregnant, asked courts could he deny paternity after a 99.9% positive test, and he has that right legally to deny. But still has to pay child support. I truly don't get why he doesn't get support is more than money especially between a dad and son, and I'd never let my son think anyone else was his dad.My son will be 2 soon. Everyone around me says forget his dad, I have clearly.. I did 3 yrs ago but they don't understand why I'm frustrated yes I have no issue moving on I just feel it's unfair to my child. I'm not denying his dad rights but at this point he won't admit paternity and I feel I should just leave him be a

nd leave the door open in future. I'm looked at as the spiteful one how?? I know there are women who do spiteful things because they are spiteful but I'm not but I can't force someone to be a parent. I know it's best to move on but do I never contact him again if he doesn't contact me?? He doesn't want his family( mom, dad, sister etc) to know about my son.
