Ugh family 😒😒

Me and my SO have been TTC for 3 months. We’ve been together for 2 years going on 3. My mom, and family know we’ve been trying since the chemical pregnancy I had. But my grandma has mad the remarks of “who doesn’t want to get married” I responded neither one of us really, we love each other unconditionally so that’s the only thing that matters. So she says “how can y’all bring a child into this world if y’all aren’t committed to each other” i respond back to just because we’re not married doesn’t mean that aren’t committed to each other. Our child will have everything she/he needs and wants. Our child will be loved. Our child will never have to do without. Our child won’t suffer. She said that I would have to drop out of school needless to say I’m about done with my associates for nurse aide. I can go through school and be a mother too. My SO has a good job, so do I working in home health. But I don’t see how not being married means we’re not committed to each other?
