Relationships are A LOT like cars

Sitting here waiting on my car to be fixed, I started checking out new and used cars. And it dawned on me just how much relationships are like cars.

I brought my car in today for a basic procedure. An oil change and a state inspection. Only to find out I need 2 new tires (which I already knew), windshield wipers, a light, and probably some brake light fluid.
Now, before I brought my car in I knew about the tires. I knew about the wipers too.
So how did this tie back to relationships?
Easy.
I knew the relationship had problems ( tires and wipers ).
And I tried fixing them (replacing) and I also tried ignoring them.
And yet it didn't work.
So, here I am shelling out $360 for my car repairs. Also looking at new ones, because I couldn't believe it.
That's exactly how my last relationship went.
I did everything I knew to do, paid my dues, and was pissed that it was all for naught.
But wait....
I'm on the lot (single) and looking for a new or gently used car (boy).

That is how it goes. Some mundane yet completely exasperating event happens in your day, and you are thrust into the realization of how simple and silly your problem was.

So here I sit waiting on my financials to come back.
Slowly realizing that paying for my car (if I get a new one) my be my longest relationship to date.
