Confused! Ugh please answer ladies

My bf well ex bf now lol were together about 2 years. I am 4 months pregnant. Anyways we bicker about small shit and break up all the time. A lot of it stems from the fact that our lives are moving on but he won't make a commitment, even went as far as asking me to pay half of the deposit to have the baby. Anyways, we broke up about 3 days ago, I haven't been taking to him him all that much but he text me now randomally as if we are friends..I'm so confused. I don't need him as my friend. He is literally the love of my life, my best friend, and I can't let go of him for some reason. I was crazy about him but he just made me feel like a piece of ass, inky hanging out wine I didn't have my kids or when he was free! but I don't want to be his friend or anything. Am I wrong, should I just ignore him?
