The thing that concerns me most is that your partner "for the most part" also wants a baby. I'd want to be having a baby with someone that wants one completely, all the time, with no possibility of them freaking out at 8 months pregnant and up and leave.

I agree, I think talking to a therapist, your gyno, and neurologist before you start trying to conceive. I'd also have a good heart to heart with your partner.
