What do you do if the relationship is just comfortable?

There’s no spark. No excitement. I don’t worry about losing him because he’ll never leave. He’s a boring person but he’s a sweetheart. He’s inflexible but helpful. He will never change but he’ll never cheat either....

Idek what to do. He’s a good guy but he’s....safety defined. He isn’t a reach. I don’t have to do much.

Thoughts?
