<human>: Give me a shortened version of the text

I think in previous relationships I've had, I would habituate to my partner's appearance. 

Ex, lets say I got together with jane way back. Initially I was very attracted to her, and over time (1+ years) I would still be very attracted to her, but it felt different. Like some kind of novelty/appreciate seemed to have gone away, which lead me to sorta feel like I was less attracted... It's confusing to me and I can't completely remember, which makes it harder to explain.

Not sure if this is related at all, but I used to/maybe-even-still have difficult appreciating presents. Like I would appreciate the gift, for like a day, but then next day I was used to the gift / novelty faded / gratitude faded.

Does anyone have any advice on how to not habituate to appearance?
