Planned to hang out w/ me but canceled plans and hung out with each other instead? do you think this is wrong?

[Serious]

ok my so called new "friends" planned to do stuff with me this weekend, but then canceled plans on me, one fo them agreed to go to a bday party on saturday and another agreed to meet with me today and now they both canceled plans, they said they're busy and couldnt meet with me, they told me they were busy with other stuff but on facebook they posted that they are together right now, and one girl kept asking me to let me let her borrow notes, and it seemed like they wanted to b my friend and planned to do stuff but i think its wrong for them to lie to me and agree to meet with me first and then cance plans and hang out together instead, it happened twice already, on halloween they planned something together without me and then i asked if one of them is going to school and she said she's "not doing well" but on facebook it says that they were out .together. should i stop being friends with them or talk to both of them? what do you think i should do?

Talk to them both and say your feelings straight out. Ask them why they've been lying and why they don't want to hang out with you. You may think this is a mistake, but you'll thank yourself later for doing it, and yes I do think what your friends are doing is wrong.

Be polite to them if you see them, but don't agree to any more plans. Just say you're busy if they ask you next time, because they don't sound reliable. If they ask why, just be honest and say you know they cancelled plans with you to hang out together & you're not into begging people to be friends. Find some other people that genuinely wanna hang with you.

you said it yourself, so called "new friends"

i would ask them whats going on
if you don't get good answers or something still doesn't feel right when you do get to hang out with them, look for better friends
