@broody19 I think the most important question for me here would be does he know you want a child and does he agree that you should try?
If so, then you're not being unreasonable assuming you can provide for the child even if you end up as a single parent.
You obviously want a child very much and if you can provide for that child then I don't agree that you have to have been in a long standing relationship before trying to conceive.
If he isn't on board, I'd consider alternatives.
