<human>: I've been going out with Brady (not real name) for six months now. I really like him and he seems really happy in the relationship too. Right now we're in the planning stages for a trip we'll take over the summer and I'm pretty excited.

So a few days ago we were at a bar with a group of mutual friends. One thing we like to do as a group is propose hypothetical situations and see how the rest of the group would respond. Like most of the time it will be things like would you eat lasagna that had been in the fridge for two weeks, stuff like that. On this given night the question that came up what "what would you do if your partner cheated." I didn't think anyone would respond to the question because I thought it was somewhat inappropriate and was brought up in a joking manner but Brady responded and said that he would break up with the cheater. This was all well and good but then he said that he would post a message on his Facebook wall detailing the situation so he could avoid people pestering him about why he broke up. Pretty much everyone at the table was nodding and agreeing like "good response, man I would totally do that, etc.". For context it was a group of both guys and girls and I would consider it to be pretty upper-class.

Since that incident I don't really feel comfortable in the relationship anymore. Brady has texted me to go on two dates since then but I have turned them down because I don't feel I can look at him the same way anymore. I know I would never cheat on him and it was a hypothetical but knowing he would so readily publicly shame someone like that was discomforting to me. I'm not sure that I can support that behavior or be with someone that does. 

I did tell my parents about this incident but they said that I had nothing to worry about since I wasn't a cheater (which is true). I just can't shake this feeling like a cloud has drifted between him and me. Am I being overly sensitive here? I feel like I see Brady in a different way although people are saying I should not.

Give me the gist of the text in a nutshell
<bot>: BF said he would semi-publicly shame someone who cheated on him. I don't feel like our relationship can be the same anymore. Am I being overly sensitive here?
