Would you break up with someone if they didn't have enough in common with you?

I’m currently dating someone who is very nice, financially well off and successful, but the initial spark I had with him has worn off because we have barely anything in common. My parents have told me they like him, his family likes me and our friends seem to think our relationship is one of best they’ve seen.

But I’ve noticed that our conversations go nowhere, and when we talk about politics he tends to have a different view than me. I’m completely fine with that, but it seems like these kinds of things make it really hard for me to connect with him as a person.

Also, I just started talking with one of my friends back home, a guy who I used to have a thing for in high school. I’m starting to realize that even though he isn’t out of college yet, we have a lot more in common and our conversations are smoother.

Do you think this current situation needs to be addressed, or should I keep dating this other guy who really isn’t bad at all?
