Nope, nobody here is normal.
But to answer the question, basically, men stop doing the little things once we have you because we don't give a shit anymore. We have already won, why bother doing anything else.
It's similar to when guys have "commitment issues." Men don't have those issues, we just prefer not to try to marry you because, well, you're just not hot ENOUGH to wake up to every morning.
Similar to when guys suddenly lose their fun personality. We realized that you weren't nearly as hot as we thought in that dark bar when we were drunk, so we cave up in hopes you'll just think we have shitty personalities, because it's kinda heartless to just say, "Hey cunt, you're ugly, GTFO."
