I would be most grateful for any advice anyone could give on this matter of deep concern to me.

For sometime now I've suspected that my wife may be having an affair. You know the sort of thing. The phone rings, I answer, someone hangs up.

Recently she has started going out 'with the girls' a lot and when I ask which girls it's always "Just some friends from work, you don't know them".

I always used keep an eye out for her taxi coming home but now she always walks up to the flat although I can hear a car setting off as if she has just got out of one around the corner.

The other day I picked up her mobile, just to see what time it was, and she went mental, screaming at me that I should never touch her phone again and why was I checking up on her.

Anyway, I have never approached the subject with her. I kind of think deep down I don't really want to know the truth.

But then last night she went out again and I decided that I would check up on her. I hid behind my car which I knew would give me a good view of the whole street so I could see which car she got out of on her return.

It was whilst I crouched behind my car that I noticed rust around my rear wheel arch.

Do you think I Should take it into a body repair shop or should I buy some stuff from Halfords and try to repair it myself?
