Boring isn't great, but then being in the middle of a crisis all the time is worse.
Can't you do something to liven things up?

What is it that you would consider exciting?

Remember your half this relationship, how it pans out is as much to do with you as him.

I mean I personally find screaming , shouting, arguing etc incredibly dull. That is my definition of boring.

I Also find some who is always waiting for me to make decisions,choices take action a bit dull.

You can't change him, but is he simply responding as a mirror to your own actions?
Maybe you need to see if he is open to more interesting things...whatever Those are.

However if this is a lack of chemistry...attraction, that's different, not alot can change that.

All the best.
