Dear Brain and Steele,

How does one know when it's time to end a relationship?  The reason I am asking is, my boyfriend and I have been together for a little over four years.  In that time, we have had unbelievably great times.  About a year ago we moved in together and things have been going very smoothly.  The bad part is...things have been going almost TOO SMOOTHLY.  By that, I mean we NEVER argue.  When we want to go out for a night, he always says "you decide where we go" or "you decide which movie".  He always says, as long as I am happy he is happy.

Some of my friends say it's the perfect relationship.  I say we lack spontaneity and a certain passion.  I've thought about bringing my feelings up to him, but how in the world do you say to someone, "it bothers me that we never fight and you always let me choose what we do."  Plus, we have invested 4 years into this and part of me things breaking up over this would be throwing that all away.  We have talked about getting engaged...but I am scared that I would become bored and we won't make it.  Am I nuts?
