advice needed

hi guys really need some advice for a serious problem! i suspected for some time now that the wife has been cheating on me. the usual signs the phone rings and if i answer the caller hangs up and going out with the girls a lot.i try to stay awake and look out for her when she comes home but usually fall asleep. anyway last night at about midnight i hid outside in the carpark behind my landrover when she came home. she got out of someones car buttoning up her blouse and took her panties out of her purse and slipped them on. it was right then crouched behind my landrover i noticed it.... a hairline crack in my front wheel. is that something i can weld or do i need to replace it?

how big is the crack, and whats it made of just as well you noticed it before it got to bad, poor landrover she more care and attention from you
