I think you gave her mixed signals by saying youd support her decision to keep the baby and be a good father. I also think if she was held at arms length for fwb only she might have successfully baby trapped you into a commitment with her.

If you really didnt want her to have a baby or a commitment with her you should have said so! Then she would have aborted it. You can also say so now by not being a good father and disappearing from her life. I mean what does being a good dad but not being committed to the mom even look like? Its vague. No wonder she assumed youd get baby trapped and start a family with her. Sorry the condom broke. I really dont think its healthy for the baby to have a noncommittal dad, so even if she were to keep it cause she wants a kid and not because she wants to trick you into commitment, it's not the best case scenario for the child to have a noncommittal dad. She doesnt sound like she respects your wishes either and keeps insisting on her own idea of the future. It sounds like a messy situation to bring a child into.
