<human>: this is the third time i've been burned like this.

and this time she did this after I told her about how this was done to me before.

Please tell me this is just badluck and not a thing girls do regularly, because I am considering giving up.

Ladies, why would a girl make weekend plans with a guy, and then ignore messages.

first time she did this, she said she fell asleep. Not the first time i heard this from a girl, but I forgave her. Because we are in medschool, and sometimes people crash.

Then we agreed to go to the movies together. SHE was the one that suggested it. Said she wanted a "movie buddy." So I agreed. 

Second time, flaked a message after the exam. she said "sorry i just saw this, I thought you meant the weekend." ok, strike 2, but plausable. Maybe I misunderstood what she meant by "after exams"

"The weekend is perfect" she says. 

Saturday comes. I asked what movie she wanted to watch, and no answer. 2 hours later, i send a "hello?" no answer. Doesnt say she "read" it, but it says she was "Active 1 minute ago" and clearly online. 

...24 hours later, now sunday night, i decided to just send a "sorry, things are piling up, cant do movies." because honestly it seemed like she was going to flake again any way.

and she is still posting stuff on facebook. she is clearly on there.

Why couldnt she just say she changed her mind instead of making me THINK i have plans.

Can someone give me insight as to why a girl would do this. This is real blow to my already-low self esteem, being single for about 4-5 years now.

Give me the gist of the text in a nutshell
<bot>: Girl made plans with me (her idea), really looked forward to a date, and now ignores messages. Being flaked on has happened to me before. Why not be direct with rejection.
