Just a weird question, but I get opened by girls often and at times ones I'm not interested in whatsoever, however I'm super polite so I hold convos and exchange socials if they ask. However I reply late to their texts ,etc since I don't want to show the wrong signals. A thing I've noticed that these same girls who message me to meet up etc at the beginning will start calling me bro a few weeks or so into talking when I make excuses, answer late. Is this a reaction to being butthurt , or a way to protect their ego? Since this has happened a fair few times to me and it's mostly these girls I didn't show interest in. It's like they keep stressing on "bro" at every chance they get and comes of as a bit try hard
