if you like one thing, don't do it at the same place, for example, don't watch movies at the same cinema, don't go clubbing to the same club with the same people, don't play sports on the same court, don't eat at the same places often. change the places, this will partially do. also, try other activities that you haven't tried before, even if you think you don't like them, cuz you might actually like them. there is a lot to try. one thing to keep in mind, you need to raise your budget to break the routine
btw, you didn't tell us anything about yourself (age, sex, marital status:P)
