This is one of the worst, and most unspoken about, feelings - a mixture of embarrassment, upset, insecurity, like someone is making a joke and you’re not part of it. Firstly, no, you’re not being “too sensitive”. It’s honestly such a **** feeling and can’t be put down to just their “banta” when they are not making you part of the joke/convo that is about you. Then it just becomes meanness or snarkiness. Honestly it sounds like the other guy is ****ed off that his friend kissed a girl and doesn’t know how to interact with you so he deflects it in weird jokes and talking bad about u etc. My best advice would be to (1) validate your feelings first (cause it’s literally the most normal reaction and you dealt with the sitch really well). And then (2) steer clear or distance yourself from the situation AKA that friend. BMT when you start not making effort with people who don’t make effort with you, or paying no mind to people who make your feel like **** or feel bad about yourself, like there’s something wrong with your personality or you have done something when you literally have done nothing wrong, life becomes so much more stress free. Sometimes it can help even to say something like “your friend is a bit standoffish” to the guy you like - I remember when one of my girlfriend’s mans was taking the **** out of my accent while I was on my year abroad and I ligit told her “he must be so insecure and childish to be taking the **** out of a foreign accent” and the next day he STOPPED. Sometimes it can help to call them out a bit then they know the joke isn’t landing how they thought it would and the facade drops. Although only do this if your sure and you kinda really like the guy and the other guy is gens c-blocking the situation or just ruining it. But otherwise ligit just distance urself from that one guy and enjoy your holiday. Don’t give the time of day to people who make you feel small so they can feel big. There’s so much stress in life and these kinda people don’t need to be a contributing factor to it.
