Is this person trying to change you to make you more like them or more like their ideal partner? Are they trying to control what you wear, or are they trying to get you to change religion? Everyone does this to some extent, but if your partner is actively and constantly trying to change your core personality and behavior then this is a warning sign. A partner should admire you for who you are and appreciate your differences – after all that’s what makes relationships interesting. If they can’t accept you for who you are, then you shouldn’t have to change.
