<human>: Summarize the given text in a few sentences.

I love this person, but they remind me of someone that I used to know from my past, someone that hurt me tremendously.  I don't trust them because things they've said on multiple occasions haven't added up.  And, this relative has a similar way of communicating with people compared to this other person from my past.  

I suspect that this relative is the type that likes collecting facts about people, making it seem like they are great confidants, only to talk about others behind their backs, or use that information against people when it's convenient for them. 

I tried to create distance when they asked me about a topic and I told them that it was weird talking about that topic when I don't even discuss it with people from my immediate family and they still wanted to discuss the topic, specifically when we cross paths again.  So, clearly that method of saying that "it's weird talking about that" didn't work, what are my other options?
<bot>: How do I create distance between myself and a relative that's around my age so that the door to discussing personal things isn't open?
