Want to ttc

I feel like I'm ready for a baby, but I don't think my SO is. He wants kids someday, but I'm afraid he'll never feel like we're "ready". We've talked about it a little bit, but he says it's a heavy topic and doesn't seem to want to talk about it much. Anyone else have this experience and how did you deal with it? I also have endometriosis, so I also feel like I don't have much more time that I can hope to concieve naturally. I know if we were to concieve accidentaly he would end up being ok with it, but I doubt that would happen as he is so careful about using condoms.
