am I wrong?

I'm putting my baby daddy on child support to try to make him be a man. He'll be 18 in march, I'm already 18. I worked, went to school, & with through this all alone. In my opinion he had all this time to get it together. I got him a job & he quite, he dropped of school, & hasn't been doing nothing good. He thinks stealing will get him somewhere but whatever. His mommy & big sisters backs him up 100%. They should understand woman to woman but they blame everything on me. I didn't make this baby alone so I shouldn't have to do this alone. He want the "father" title & LOVE telling his friends I'm his "baby momma" but don't want to take care of his responsibilities! Everyone says "what do you expect from a 17 year old" but why do I have to drop my life & he doesn't. I hate how society expect the moms to break their backs for their babies but the men can just live their life free. Share your opinion. He'll either get a job to help or just go to jail, idc. I just want him to see that this is not a joke.
