Love was a cracked head gasket

Years ago you became my nemesis
Now in matrimony we have an alliance
From a midsummer's nightmare to a sweet dream
In an ironic twist you are the best thing to me
You covered my meal, which was more than enough
It turned out to be more than five bucks
I then gave you that ring
And you gave your heart to me
Love was a cracked head gasket
Now we have all we have in one basket
Baby your love now does go far
And we both drive decent cars
