Coparenting advice

I have a 7 month old daughter and the last year and 7 months haven’t been easy for me. My child’s father and I found out i was pregnant in February last year, he was scared, nervous and every emotion you expect to be being in college and having a baby. He lived in Louisville for school and would come home weekends. We were already in a rough spot in our relationship because i lied to him over school and sports. But it wasn’t anything too serious, or something that should matter now. Well we split when I was 4 months pregnant. My daughter is now 7 months and it’s so hard for me to coparent with him because i have emotions still and I still have hopes for my family. I grew up in a split family and having two of everything sucked. His parents are still together doing everything as a family so he doesn’t get what it’s like to be bounced around. I am dying to give our family a chance for our daughter. Am i wrong for wanting this chance? Does my daughter deserve this chance? How big is parents being together important for the baby? I’m so stuck, i just want to make our coparenting better.
