Mistake or Blessing?

I dont want any hate but I just need to tell someone my thoughts. I'm freaking out. I graduated high school when I was 17 graduated college in August at 18. I turn 19 soon Anyways I found interest in one of my really good friends who just turned 33. Things led to another and we werent the safest one night. I'm now 4 weeks pregnant. I dont want to just start a relationship because of this and I'm freaking out because I dont want to hear all the shit about the age difference. And I'm freaking out because I dont know I'm so broken hearted and torn on what I want. He wants a child because hes older so I know he would try to be in the child's life, but I dont want to pursue a relationship right now. Do I bring a child into a nonexistent family or do I save a child by not even bringing it into this world. Any tips?
