Guy used “gay” as an insult. What do I do?

k • 19

So I literally just started talking to this guy I met on tinder and were talking and he’s super sweet and we have a ton in common. I told him something bad that happened to me once and goes “that so gay lol” and I literally almost threw my phone. Really? I usually would just block the guy and forget about it, but I’m trying a different approach. I said “don’t use gay that way” instead of letting it slide. I’m not experienced with guys AT ALL LIKE IVE NEVER HAD A BOYFRIEND so I’m wondering do I cut him off now or see if I can teach him not to be hateful like that. Girls please help a fellow female doesn’t know what to do.
