I feel so guilty for continuing the cycle

I’m 8 weeks pregnant with my first but one thing plays on my mind relentlessly. My baby will grow up just like I did no father and I feel so incredibly guilty about it. My dad left us when I was a newborn I had a stepdad and a little brother but he left so I had absolutely no father figure. I’ve done the same to my child. I always wanted something different for my kids the father is a coworker of mine one night stand drunk after a team dinner he was dating another coworker the two were on a break at the time. Please don’t rip into me for that because I know how incredibly stupid it was of me to put myself in that situation. He’s a good man truly but I already feel the cycle restarting I’ve made my bed I have to lay in it now but I can’t help but feel guilt for it but all I can do now is my best for my baby.
