If you can’t remember what you liked before you started dating them, take a weekend to find out.

People merge faster than they notice. Spending most of your hours with one person makes their taste the default, and after a while you cannot tell which parts were ever yours. That is not proof anything is wrong, only that something of yours has gone untended. What you liked first is usually still there, just out of the habit of being chosen.

Give yourself a weekend where you pick everything, the music, the food, how the hours get spent. Do one thing you liked before and have not done since. Coming back with something of your own is good for both of you.
