I vaguely recall reading a do-over/time travel type series of stories with an interesting premise.
The male main character would go back in time, but not to his direct past/body and live a parallel life up to a point. Once it made it to that point, he was able to go back and do another parallel life in the same universe. I think there were 2-3 or maybe more stories in the series. From what I recall I think his significant other/wife/GF was able to also go back with him as of the 2nd or 3rd story.
I also recall in the last story he met or realized one of the other characters was also able to do this and was watching what he would do. Or something along those lines.
Been poking around the net for a few months and just cannot recall/find it. Any help?
