A difficult decision to make..

I’ve never written this like before, but I really need your advice on what could be a crucial decision.

I’ve suspected for some time now that my wife has been cheating on me. The usual signs. The phone rings, but if I answer, the caller hangs up. My wife has been going out with the girls a lot recently, although when I ask their names she always says, “Just some friends from work You don’t know them.”

I sometimes stay awake to look out for her taxi coming home, but she always comes walking up the drive as I hear the sound of a car leaving, around the corner, as if she has gotten out and walked the rest of the way. Why? Maybe she wasn’t in a taxi at all?

I once picked up her cell phone, just to see what time it was. This caused her to go completely berserk. She quickly snatched the phone out of my hand and cursed me hysterically, screaming that I should never touch her personal property. She then accused me of trying to spy on her.

Anyway, I have never broached the subject with my wife. I think deep down, I just didn’t want to know the truth, but last night she went out again and I decided to really check on her.

I decided I was going to park my motorbike next to the house and then hide behind it so I could get a good view of the street around the corner when she came home. It was at that moment, crouching behind my motorcycle that I noticed a small amount of motor oil leaking through the gasket between the rear head and rocker arm cover.

So, is this something I can easily repair myself or do you think I should take it to a garage?
