I want to make her lose interest in being friends with me

So im working in my work place for 4 years and its been a month that we have a new security. She is 13 years older than me and we have completely different life styles. Im not saying she is a bad person she is just not my type of a person Days ago she started telling me about her relationship problems out of nowhere and i wanted to be nice so just gave her some simple advices. Now she wants to meet me out of work place and call me after the working time which im not interested to because im really picky when it comes to friends. I need advice on How do i politely make her lose interest in being friends with me. I need it to be really smooth because im gonna see her everyday. Any excuses for not making plans at the weekend with her …
