Co parenting with someone who hurt you

Tae • Baby Girl due Jan. 16th 💕🎀
So the father of the child I'm currently carrying was living a double life I had no clue he was in a relationship with another woman and now we have to raise a child together but at the same time I'm still hurt by the way he lied and played me how do I get past what he did to me and raise our child together without being petty? Please comment or let me know if anyone has been through something similar
