Unfortuntely, there's no actual method to figuring out where you are with each lady. I could say use the hint system, but, that's not exactly reliable.
If you are able to recall the last thing you did. you could find where that falls in, in the walkthrough, and grab the corresponding save from my signature.
Beyond that, unfortunately, other than going to each female character at each time of day, seeing what options are available, crossing out the parts in the walkthrough.
My advice, other than starting a new game, would be to grab my "Completes 0.34" save and start from the beginning of 0.35 of the walkthrough. since according to you is the last update of the game you played.
