Advice Needed, Serious replies please

Hi All,
I need some advice on what could be a life changing decision.

I've suspected for some time now that the missus has been cheating on me.
The usual signs. Phone rings, I answer, someone hangs up.

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

I always look out for her taxi coming home but she always walks down the road although I can hear a car setting off as if she has just got out of the car round the corner.

I once picked her mobile up just to see what time it was and she went beserk 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 her.
I think deep down I just didn't want to know the truth but last night she went out again and I decided to check on her as it was killing me.

I decided I was going to hide behind my van which would give me a view of the whole street so I could see which car she gets out of and who was in it.
It was whilst crouched behind my van that I noticed rust around my rear wheel arch.

Should I take it into a garage or should I buy some filler from the local Halfords and try to repair it myself?

Any help would be appreciated, Thanks
