I agree with Bill, acknowledgement and acceptance may be the best way here.

It sounds like you made some real progress the last few days, set backs are inevitable, try not to be too discouraged by those.

It's really encouraging your wife wants to spend more time with you it shows she is still invested in your marriage - it's when people no longer care there are real problems. I know you say you're busy but how much of this are commitments you can't get out of? I recently felt I was busy too but chose to shelve some of my leisure time to spend more time with my spouse. I did enjoy my sport activities but decided my marriage was a priority. If there are things you can shelve then I'd do it, your wife is telling you she'd like more time with you, I think it's wise to listen.
