This is a very sweet thread. It looks like your wife is afraid that you're hurtin' for it. But if you say you're not, you're not!
Hear that, Mrs. OhSnap? You can stop throwing twats at him now. He doesn't seem to be interested.
Also, Mrs. OhSnap, I'm very sorry that you've had to deal with such a lifestyle change. If you were active before, and now you're forced to be sedentary, that can be a real adjustment where you just don't feel like "you" anymore. I hope you are seeing a counselor or something to talk about the real grief you must be feeling for your "old life".
