I understand that (as much as I possibly can), but there’s really no good answer here. If it’s 100% pull the trigger or bust, then I he shouldn’t marry her. Communication is such a crucial aspect of a relationship that he needs to know whether they can communicate effectively. With that stutter, it’s just not possible to tell right now. Maybe it gets better with speech therapy. Maybe it doesn’t. Maybe he is great at listening to people through a stutter, maybe he can’t stand it. He needs to know before making a decision. I used to date a girl that I was *crazy* about. Expect her voice. Her voice was like nails on a chalkboard for me. I tried to get past it for a couple months, remembering the reasons I liked her in the first place. Eventually, I had to break up with her because I just hated having conversations. It sucked, and I felt like a total asshole for it (I didn’t tell her obviously), but if you can’t communicate with your partner, you don’t really have a relationship.
