I don’t know what she wants from me but I’m done, I give up and she is blocked

We are long distance, I’d say we were best friends, not dating, at this point cause the dating attempt didn’t work out after last time I tried to walk away due to the lack of effort on her side saying I feel like this is one sided. She got so upset and after a month or so, we started talking again but I have kept it more platonic than our first time around.

She would always have these moments that made me really question what is going on here like things are great then a weekend happens and she lives a different life, I ask about it and she gets super defensive.

I feel like she just uses me cause the way I treat her and help her (we work together). On the weekends she goes ghost for half the day or even longer but usually always replies at the end of he day but during the week will text all day and night and be on the phone for hours. I don’t get mad or ever say anything either cause I know she is probably just busy.

Yday was her birthday and we always sent each other gifts, she received mine which was a super thoughtful gift nothing expensive, the day before and sent a super long text saying thank you, how lucky she is this and that blah blah blah. The same exact day, she went out with her friends to celebrate (which I didn’t care about, didn’t expect her to respond during that time) BUT what she did do which really made me feel dis respected was, she hid her stories on her instagram from me while she was out. Last time she did this I asked in a nonchalant way and she basically was like “I don’t feel like posting as of late” and I just ignored it (I know how dumb) but this time was crazy timing cause she posted for her birthday, saw the story and then all of a sudden it disappeared and all her highlights were gone so I knew and was like wow okay and hasn’t texted back since and it’s been almost 24 hours and we were having a conversation. I saw one of her friends story and she had someone with her (a guy) I hadn’t seen before and wasn’t one of her usual friends she is with SO I just blocked her.

Not going to say anything and she is gonna be so upset when she realizes but I am not a person she can just keep stringing around. Clearly her priorities are else where and it’s time for me to move on. A friend or whatever we were wouldnt act different when they are with someone else. She would text her friends when we were together, why is she hiding stuff from me if we are just friends? What doesn’t she want me to see? If she is with another guy, just emphasizes what I tried telling her before that there is no point for us to be just friends if you’re just going to drop me when you find someone you like. Not doing this back and forth. Not sure but I don’t care anymore. Really sucks but I can’t force someone to do anything they don’t want to do. Feels like she just wants me around for when she doesn’t have anyone to entertain her and I quit.
