Do i need to move on

Was dating this girl for 2 months, went on about 7 dates with each. Couldn't see her every week because she had her kid week on, week off with her ex. We pretty much texted everyday, just to see how each others day were going.

We had a date setup and she texts me "can't make it".. Im like oh ok, hope everything is ok. So I leave it for a couple hours thinking somethings wrong. Later that night, find she removes me from Facebook. So i text her, hope everything ok, see you removed me off Facebook whats the deal? No reply at all. I wait 2 days and send her a long text explaining thought things were going well, etc.. We were flirty texting and everything the night before our planned date the next day and things were going well..

My question is why would she just blunt out start ignoring me, when i did nothing wrong and from my understanding things were going well, judging by the texts and stuff she was sending me and when we met and person, she liked being with me. She even said i would like her kids when the time came and stuff.. Is there really any reason to not give a reason? or is she just being immature?

The thing is its been over 2 months since i last talked to her now, but i miss her.. Ive wanted to text her so bad and just say something. For some reason i thought she was the one for me cause of just our interests and stuff alone and it was so easy being with her. Any suggestions
