You know, some people might just be committed and love their SO but still go out to bars and clubs and find the shirt funny and possibly useful. But the shirt isn't inherently saying my SO is jealous. If it said boyfriend and a girl was wearing it would you say the same thing? Most times no.
Overall some people enjoy their SO and has no intention of cheating and like the idea of just showing their commitment publicly :)
I wasn't talking about the songs meaning that last bit in your conclusion, the songs were brought up to inform that she just had a lot of romantic partners. Honestly you have a promising career in fiction writing with how far your imagination takes you since nowhere in the post do I insinuate songs means she's had "sex all day with thousands of men" but yes other then your conclusion you've made you brought up some good points, this was just meant to be a slight and quick correction for someone who just didn't know something under a right wing hate post.
Have you forgotten that like a lot of her early work was like romance and break up songs (until a while ago she was struggling to escape being known for just that), she's just had a lot of partners and they have or had their previous partners talk about the sex life.
Fair enough, I guess I'm just introverted enough to not have that realisation occurring by myself. Thanks for your response. Have a good day :)
