Pregnant and getting divorced

I've been separated of my husband for 6 months after 4 years of marriage, he's living in our house and I moved out , we are living completely separated lives, he's dating someone else and I also started to date, on Monday I finally filled the divorce, but today I found out I'm pregnant.

Odviusly my legal husband is not the baby's dad.

Is my pregnancy going to affect the divorce process? I don't want anything from my husband, just the divorce, he can keep the house and the car, and of course I'm not putting him on child support. I live in Massachusetts
