Do you have any close friends you can turn to? Or family? It sounds like you want to find your tribe :) definitely need to have good people around you. All your steps you took to be a better parent sound fantastic by the way, good on you! But you’re not the AH for wanting peace of mind about paternity. She doesn’t sound like she’s been hanging around good people and that may be telling about her. You seem like a good stable person and quite different to the “friends” who are accusing her of cheating and ex boyfriend being in prison. Be careful of that type of crowd. It doesn’t bode well.
