Should i stop trying ?

I'm currently 24 weeks pregnant me and my child's father did not work out because of cheating ( getting someone else pregnant ) and constant mental abuse I recently asked him to purchase a mattress for our sons crib because I'm putting his room together within the next few weeks his response was "y'all are getting on my nerves" referring to me and his other child's mother but I haven't even been speaking to him I just felt like he can buy things just like I can I didn't make my son by myself although that's how he makes it seem should I just stop trying ? I feel like I'm trying to force something that will never happen.
