Why do I feels so guilty?

My ex and I were married for about a year. We're getting a divorce because he became very abusive towards me. Well in about 2 weeks I will be giving birth to our daughter. He has no idea that I've been pregnant and about the baby. I don't want him near her because I fear of what he might do to her if I'm not there but yet I feel this overwhelming guilt that I just can't shake off. When I come close to telling him I just remember all the horrible things he did to me and get scared for my daughter. Am I wrong? Please no judgement...
