Pregalimony- pregnancy alimony

My baby's father broke up with me and was cheating on me( he wants to be with her) I just found out this week. We are not rich by any means but now I'm in even more of a hard situation because I'm on my own, and I have no idea how I'm going to cover the expenses of moving, or a new crib ( he won't let me have the one we originally got he did pay for it- he wants it), a car seat, and other baby supplies I'll need that I don't get at the shower. I feel so angry that he's ruined everything and there is seemingly no consequence for him- we lived with his friend so I had to be the one to move, and I have to deal with all the strife and costs of relocation. And it's hard because my parents say I should just not talk to him, for my own heart and healing but I'm 26 weeks and I feel like I'm running out of time. Should I ask him for financial support during pregnancy? Has anyone gone through this?
