Pregnant and heartbroken! Please give me some advice.......ladies

I want to share this because I need some relief.........I found out baby's father was cheating on me. I'm so hurt because he has never flipped out on me like this. I feel so alone and betrayed. I'm pregnant with his third child. We've been together for 2 years and then he waits til now to hurt me. Why? I have so many questions but I've called him enough. Ladies I refuse to keep calling a person that won't explain himself because he knows he's busted. I'm praying for the strength to move forward in my life. All I want is love and support right now. Praying for peace as well! Any advice ladies?
