Am I wrong for putting him on cs?

Am I wrong for putting my bd on child support? When he first found out I was pregnant he kept telling me to abort and then denied it was his. He ghosted me for a the first months. He came around at month 3 and then 3 weeks passed by and I found out he cheated on me and had told his bitch I was delusional and the baby wasn’t his. Normally I’m a very independent woman who has done things herself but the more he denied my baby the more I wanted to put him on child support so for life he’ll have a reminder financially he has a child and won’t be able to forget it forever. I want the court to force him to get a dna test to prove it’s his. I want him to eat all the words he has spat at me. I feel spiteful right now even though I shouldn’t….

I was dating this guy for 4 years and once I became pregnant he completely switched up on me and ghosted me throughout this whole pregnancy. I’ve spent most of my pregnancy crying
