<human>: Bear with me, this is hard to summarize.

So... we've been married for about a year and a half, together for 7. I love her (or at least did...) more than I can express. I am founder/CEO of a company for 5 years and work a lot. For almost two years, my work became very obsessive, to the point where I wasn't seeing my wife as much as I should have been. She got a job as a cook, which made this even worse (she was working 6 nights a week until 10pm, sometimes going drinking after until 1-2.)

At first her job just made me work even more. She ended up getting upset/depressed we weren't spending time together, I was a bit neglectful of the relationship, so she sat me down for a talk 4 months ago. After that, I made dramatic changes, cutting my hours at work back from ~108/week to ~44/week. I tried much harder to show her she mattered to me, to spend more time with her, but it was hard, since her schedule was so conflicting. We still hardly saw each other, and my suggestion she try to work different hours or quit made her angry (not supportive of her.) So essentially she didn't help us see each other more.

Finally, about a month ago, she quit to work somewhere else with better hours. I was thrilled, seeing this as an opportunity at last for us to spend real time together. But she was distant... strange. Would just watch TV all night. Then I find out through a friend she had been cheating on me for at least a couple months with another cook. She admitted to it as soon as I knew. Supposedly she broke it off with that guy, wants to try to fix things with me.

I'm taking this hard. This guy was a 32 year old (we're both 27) line cook, probably illegal immigrant, going nowhere. I have worked my ass off, and have a lot to show for it. I can give her whatever she wants, and want so badly to make her happy. Why did she do this to me? And why with this guy?

Can you condense the text into a few key points?
<bot>: Loved wife very much, weren't spending enough time together because of work, she cheated on me with a co-worker, now wants to try to fix our relationship.
