Serious problem

I have suspected for some time now that my wife has been cheating.

All the usual signs; phone rings, if I answer the caller hangs up, going out with the girls a lot, etc.

I try to stay awake to look out for her when she comes home, but I usually fall asleep.

But last night, about midnight, I hid in the shed behind the Spitfire

She got out of someone’s car buttoning up her blouse, then she took her panties out of her purse and slipped them on.

As i was crouched down behind the Spitfire`i saw a crack in the corner of the wing are they expensive to replace?
