Heartbroken, betrayed and devastated

My boyfriend of 6 months(although we’ve been pursuing each other for a year) just revealed to me that his ex girlfriend is pregnant. He said the pregnancy is early and he’s known for about a month. I’m completely devastated and heartbroken and unsure how to move on. I was under the impression we were in love, committed and getting ready to move in together. It’s been 3 days since he’s told me and we haven’t spoken since. Although I know our relationship is clearly over, I just feel like I can’t comprehend anything. We spent so much time in communication so I can’t even figure out how, when or why this happened. I find myself crying at least once a day since I’ve found out and can feel the pain of heartbreak in my chest. I just feel so lost.
