It sounds like your baby daddy isn’t into open relationships. I don’t think his method for communicating it was on point, but he doesn’t sound like a psychopath from that post alone. At the end of the day, once you have that kid…you’ll realize that your life isn’t just about you anymore. The most important job you’ll ever have is to make sure that child has everything they need, including your unconditional love and a healthy, supportive environment to grow up in. You’ll figure it out. Good luck, soon-to-be mamabear!
