I thank everyone for their advice and opinions. I'm a little taken aback with all the marriage talk. In my opinion, at 24, asking for the major life changing decision of having a child with me is more than enough let alone pressuring him to marry me. For some to elude that because we aren't engaged or married yet means that he is not committed to me is crazy.
If my concern was him not proposing I'd be on another site.
I don't need to second guess his commitment to me. It's not about that. It's about his readiness for children and my time frame
