Spark is gone but your still here (help, i'm missing a word)

When I first met you I never wanted to be without you
I wondered why I had felt like that.
Usually I could care less if I have someone or not.
As time went by the fire burnt out.
Now we're stuck, well I feel like I am.
We are always so relaxed with eachother,
it always just feels normal, the excitement is gone.
We're still together now in this love/hate relationship.
At this point, that is what it has become.
Now looking back to when we first met.
You were my *rebound**
And now you're my security blanket.
I use you, I don't want to, but I do.


*Sorry, I can't think of the right word i'm lookin for, if you know it please feel free. It's the word to describe someone who just broke up from a serious relationship and quickly gets into another to help forget about the other one.
**nevermind I got it now, thanks for stoppin in and reading.
