Co parenting

I’ve been trying to co parent and be the mature parent but its just not working out for me. My daughter father didnt sign her birth certificate and made a big fuss about not being about to do a dna test at the hospital. I’ve finally found a job that would fit my schedule so I can have time to spend with my baby. I only worked 2 days and today her father was suppose to get her and now Im pretty sure I’m fired because I have to stay home. Its so hard trying to make it all work when I didn’t make this baby on my own but he only wants her when he wants to show her off to someone. I just need advice 😢 or words of encouragement.
