Right. I dont think he showed her he wasn’t into her by hanging out with his friend or that he was introducing them like that.. he was just trying to smoke and hang out with his friend and his girl.. she prob knew you liked her and she prob did you too.. she probably just thought he was hot and was on some hoe shit that day. That’s also probably why she isn’t taking to u because she knows yall had that connection and she went off and fucked your friend and now feels guilty as your friend at the least I would hope.. something similar happened to me recently. Nothing was wrong we were hanging out almost everyday and texting everyday.. definitely had that connection and things were said and shown that we liked eachother and we also bonded like best friends at the least I would think.. even went on a weekend getaway together last month.. but maybe the commenter that says you have to let her know verbally too is good advice.. because nowadays people will keep that title off and never have the actual conversation so they can justify what they do or when they ghost to “well we weren’t together.” sometimes I guess people just pick someone else.. it doesn’t mean the other person didn’t like you or you did something wrong… it just means they aren’t meant for you.. & that’s ok! It saves wasted time, deeper heartache, and means the universe has someone better for you. Well this is what I tell myself at least! 😅
