Doing it on my own

I found out I was pregnant over the weekend. I was scared to tell my boyfriend but finally cooked up the courage to do so. When I did he seemed ok just scared. We were great during the weekend until Monday. His whole demeanor changed and now its all my fault and I pressured him into having a baby. Omg it's been a damn nightmare. We have two kids. One is his and the other is mine. We have been together for almost 2 years. But the catch is that he is my very first boyfriend from when we were younger (12 &13 years old). This sucks 😕 and im an emotional wreck 😢. I needed to vent to someone. I appreciate you listening!
