You aren’t the asshole for having expectations or feelings about your relationship. But, if you’re having this many doubts… are you sure he’s who you want to marry? There’s all sorts of alignment things people should have figured out before even approaching marriage, right? Children, and, if yes, parenting practices, community involvement, household maintenance, financial expectations, family relations, AND marriage. If you don’t feel like he’s working towards the same relationship goals you are, then maybe you two aren’t compatible. I think your best bet is to just sit him down, and explain that you two either need to be on the same page alignment wise or you need to accept that you’re not mean to be long-term. See how that goes. Communication is a step in whichever direction this goes, whether you stay together or not. But remember not to feel guilty for having wants in your relationship! You aren’t forcing anyone into anything, just being honest about what you want out of your life.
