I've suspected for some time now that my girlfriend has been having an affair. The usual signs: Phone rings, I answer, caller hangs up. She started going out 'with the girls' a lot recently although when I ask which girls, it is always "Just some friends from work, you don't know them." I always look out for her taxi coming home, but she always comes walking up the driveway as I hear a car setting off...as if she had exited the car 'round the corner. Why? Is it not a taxi? I once picked her mobile up just to see what 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 g/f. 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. I decided I was going to hide behind my car which would give me a view of the whole street so I could see which car she gets out of. It was whilst crouched behind my car that I noticed rust around my rear wheel arch. Now, should I take it into a body repair shop or should I buy some stuff from the local auto shop and try to repair it myself? Use bondo?
