Engaged and need advice

I am full of anxiety and was wondering if anyone on this sub can help me.

I’m a 22F Bais Yaakov graduate and got engaged a few weeks ago. We dated for two months. While we were dating in the back of my mind I started wondering if we might not have enough conversation to carry us, but I was good at generating discussion so I mostly ignored my feelings. I figured that marriages don’t depend on conversation and we would figure it out somehow.

The problem is that now that we’re engaged I’m realizing that he really does have a hard time generating discussion and more than that, he just doesn’t have a whole lot going on in his head – mostly his work and his hobbies. We talk about three times a week and after about an hour and a half we have nothing left to talk about. This is causing me intense anxiety.

I keep thinking – would I be able to live with a husband who I just don’t have stimulating discussion with? Am I going to be miserable for the next N years? Will I end up getting divorced (c”v) and be a single parent? Should I just break the engagement now and save myself the trouble?

In my community a broken engagement is a huge thing and a major embarrassment, and it’d be very hard to ever get a date again. And how would I justify it – “he wasn’t an interesting conversationalist”?!

I would really appreciate any advice from anyone who has some to offer.
