Do I wait her out?

[Stubborn-Male]

Hi GR8,
After the operation to remove infected kidney i started on ant-cancer drugs to kill the affected areas on my spine; I had one vertibrae 50% eaten away. I am also on special bone growing drugs; the latest scans I had show that most of the vertibrae has grown back! No sign of any other cancer on the scans or blood tests, so fingers crossed though I will be on drugs at least until Xmas. I am still physically weak and tired.
Infidelity, mmmm. I really don't know. My wife is very involved with social activities, mainly with people I know; I think if there is someone it is very, very secret. Her family, who I talk to frequently, insist there is no one else. It's difficult to verify without stalking etc.
I have not found Puppys advice, a link would be helpful, thanks.
