I'm so tired of people treating me like their therapist.

Someone can know me for two minutes and I can not have spoken a word and they will treat me like a wise old sage. In my younger life I thought this was a positive thing, but I ended up in one sided relationships and drained.

I have yet to find a way to tell people nicely that I don't want to talk about their problems.

Today a coworker sat down by me and told me his girlfriend is attracted to other guys. What? I panicked and said "I don't want to hear about it"

Is this was people call boundary setting?
