Is this the right behavior for the workplace?

I am currently employed at a restaurant as a dishwasher. I have become acquainted with most of the people there so far. The one woman there who everyone calls Warner likes to make the talk into dirty talk and really no one has a problem with it. Warner and my boss Tyler for a while were joking around pretending to be married. They told me over and over again how they are together an I took it seriously believing them. So since I thought they were together I began to like this other girl working there Named Briana or Bri. The one night I asked Warner if Briana was single and I thought she was cute. She agreed with me how she is a cute girl but she already has a boyfriend. I asked who. She then told me her boy friend was Tyler. I got a little annoyed saying how I was told you and Tyler were together. She then joked around about it even though I was pissed. She told me how I better stop looking at her or Tyler will kick my butt. I was angry and embarrassed at the same time. Now I have to go into work with that on my shoulders and feel weird every time I am around Bre or Warner. I also have to worry about Tyler finding out. What should I do? And was it wrong what they did too me?
