As someone who loves games but doesn't look for a challenge . . . you can always cheat? It's not that hard. I mean for the secret ending you would have to set several variables (looking at the file you need to set the values of 14 variables (since excess friendship for adam, steve and tom are separate) which you can do in game with a dev console or just get to last day without dating anyone (since that flag would be checked first) and then save edit that save.
If you want I can post what exactly to do (can we do PMs or do spoiler text here?)
Always play the game at least once as the dev intended since it is their vision but if you still can't get what you want out of it, get creative:) That's my stance on (non-competitive) gaming anyway.
