I've never written to you 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... 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 always stay awake to look out for her taxi coming home, but she always walks down the drive. Although I can hear a door slam and a car driving off, as if she has gotten out of the car round the corner. Why? Maybe she wasn't in a taxi? I once picked her cell phone up just to check the time it was and she went berserk and screamed that I should never touch her phone again and why was I checking up on her.
Anyway, I have never approached 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 classic Galaxie convertible outside by the garage and then hide in front of it so I could get a good view of the whole street when she came home. It was at that moment, crouching low in front of the car, that I noticed that the engine seemed to be leaking a little oil.
Is this something I can fix myself or should I take it to a professional mechanic? What do you think?
